Insektisida adalah cara yang tepat untuk mengatasi hama tanaman berupa serangga. Insektisida adalah bahan kimia yang dirancang khusus untuk membunuh dan mengendalikan serangga yang merusak tanaman. Dengan menyemprotkan tanaman menggunakan insektisida, serangga-serangga tersebut dapat dibasmi dan tanaman dapat terlindungi dari kerusakan yang disebabkan oleh hama serangga.

CVPD stands for Citrus Vein Phloem Degeneration, which is a disease that causes damage to the sieve tubes in citrus plants. This disease affects the transportation of nutrients and water within the plant, leading to stunted growth, yellowing of leaves, and ultimately, death of the plant. The other options mentioned, such as virus belang, bulai, and jamue armelaria, do not specifically cause damage to the sieve tubes in citrus plants like CVPD does.

The correct answer is 3 dan 5. Based on the given information, the parts that function as a transport network are indicated by numbers 3 and 5.

Hidrotroppisme positif adalah pertumbuhan ujung akar yang bergerak ke arah sumber air. Ini berarti akar akan tumbuh menuju air untuk mengoptimalkan penyerapan air dan nutrisi yang dibutuhkan oleh tanaman.

The correct answer is "rambut akar – xilem akar – xilem batang - daun". This is because the sequence of transportation of water in plants starts with the absorption of water through root hairs (rambut akar), then it is transported upwards through the xylem in the root (xilem akar) and then in the stem (xilem batang), finally reaching the leaves (daun).

The correct answer is 6 CO2 + 6 H2O ------------ C6H12O6 + 6 O2. This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of sunlight and chlorophyll. This equation accurately reflects the balanced chemical reaction that occurs during photosynthesis.

The correct answer is "Menutupnya daun puteri malu setelah disentuh" because it describes the movement of the Mimosa pudica plant, commonly known as the sensitive plant or touch-me-not. When the leaves of this plant are touched or disturbed, they quickly fold inward and droop, giving the appearance of the plant being shy or "closing" itself. This response is a defensive mechanism to protect the plant from potential harm or predators.

Kaliptra berfungsi sebagai pelindung akar. The kaliptra is a protective cap that covers the root tip and helps to protect the delicate root tissues as it pushes through the soil. It acts as a shield against mechanical damage and pathogens, ensuring the root's survival and growth.

The given answer states that the difference between dicotyledonous and monocotyledonous plants is that dicotyledonous plants have cambium, endodermis, xylem, and parenchyma tissues, while monocotyledonous plants do not have these tissues.

The correct answer is "air dan garam-garam mineral diangkut dari akar ke daun melalui pembuluh xilem". This statement correctly describes the process of transportation in plants with seeds. Xylem is responsible for transporting water and minerals from the roots to the leaves. This process is essential for the plant's survival as it provides the necessary nutrients and water for photosynthesis and other metabolic processes.

Lingkaran tahunan adalah garis-garis yang menunjukkan hasil kegiatan dari suatu masa pertumbuhan pohon. Lingkaran tahunan terbentuk oleh perbedaan densitas xilem pada musim pertumbuhan yang berbeda. Setiap tahun, pohon membentuk satu lingkaran baru yang dapat dilihat melalui potongan melintang batang pohon. Jumlah lingkaran tahunan dapat digunakan untuk memperkirakan usia pohon.

The correct answer is fotonasti. Fotonasti refers to the non-directional movement of a plant or plant part in response to light. In this case, the flower of the Mirabilis jalappa plant blooms only at 4 pm, which indicates that it is responding to light cues. This response is not dependent on the direction of light, but rather the presence of light itself. Therefore, the movement of the flower in this scenario can be classified as fotonasti.

The structure X in the given anatomy of the root is responsible for expanding the area of water and nutrient absorption from the soil.

During the process of photosynthesis, plants take in carbon dioxide (CO2) from the air. This gas is essential for the plants to carry out photosynthesis, where they convert carbon dioxide into glucose and release oxygen as a byproduct. Nitrogen (N2) and oxygen (O2) are also present in the air, but they are not directly used by plants in the process of photosynthesis. Water vapor (H2O) is important for plants as well, but it is not the main gas that plants take in during photosynthesis. Therefore, the correct answer is carbon dioxide (CO2).

The correct answer is "Hasil fotosintesis diangkut melalui floem yang terdapat dikulit" because the presence of white bumps on the upper cut surface indicates that the transportation of photosynthesis products is occurring through the phloem, which is located in the skin (bark) of the plant. The xylem, on the other hand, is responsible for the transportation of water and minerals, not photosynthesis products. Additionally, neither the phloem nor the xylem serve as storage sites for photosynthesis products.

Fotosintesis adalah proses di mana tumbuhan menggunakan energi cahaya matahari untuk mengubah karbon dioksida dan air menjadi glukosa dan oksigen. Dalam proses ini, energi cahaya diubah menjadi energi kimia yang disimpan dalam glukosa. Oleh karena itu, jawaban yang benar adalah "cahaya menjadi energi kimia".

The statement "gerak batang dan daun yang mengarah pada datangnya cahaya" describes positive phototropism because it refers to the movement of the plant's stem and leaves towards the direction of incoming light. Positive phototropism is a growth response in plants where they grow towards a source of light.

Floem adalah jaringan yang berfungsi mengangkut hasil fotosintesis seperti glukosa dari daun ke bagian-bagian lain tumbuhan yang membutuhkannya. Jaringan floem terdiri dari sel-sel berbentuk tabung yang disebut elemen floem. Elemen floem ini berperan dalam mengangkut nutrisi dan zat organik melalui proses translokasi. Oleh karena itu, floem adalah jaringan yang tepat untuk mengangkut hasil fotosintesis dalam tumbuhan.

not-available-via-ai

The correct answer is "menghasilkan oksigen". This is because the experiment aims to prove that photosynthesis produces oxygen. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. In the experiment, if the presence of oxygen is observed, it confirms that photosynthesis is occurring and producing oxygen as a byproduct.

Tigmotropisme adalah gerakan tumbuhan yang disebabkan oleh rangsangan fisik seperti sentuhan atau tekanan. Pada markisa, sulur tumbuh membelit, yang menunjukkan adanya gerakan tigmotropisme karena tanggapan terhadap rangsangan fisik tersebut.

The boiling treatment in alcohol is done to dissolve the chlorophyll granules. Chlorophyll is a pigment responsible for the green color in plant cells. By boiling the leaf in alcohol, the chlorophyll granules are dissolved, making it easier to observe and study other components of the leaf. This process helps in understanding the structure and function of the leaf and its various components.

Autotrof adalah organisme yang dapat mengubah zat anorganik menjadi zat organik. Ini berarti organisme tersebut mampu melakukan fotosintesis atau kemosintesis untuk menghasilkan makanannya sendiri tanpa perlu bergantung pada organisme lain. Dengan kata lain, autotrof dapat menghasilkan energi dan nutrisi yang diperlukan untuk kelangsungan hidupnya dari sumber daya anorganik seperti air, karbon dioksida, dan mineral.

Haptonasti is the correct answer because it refers to the movement of plant parts in response to touch or contact. In this case, the movement of the kantung semar (pitcher plant) closing when an insect enters is an example of haptonasti.

The correct answer is that the vascular bundles in dicot stems are separated by cambium. Cambium is a layer of meristematic tissue that is responsible for secondary growth in plants. It produces new cells that differentiate into xylem and phloem, which make up the vascular bundles. In dicot stems, the vascular bundles are arranged in a ring-like pattern, with the cambium layer separating them. This allows for the growth of secondary xylem and phloem, contributing to the increase in girth of the stem over time.

The correct answer is "dikotil batang tidak bercabang, monokotil bercabang". This is because one of the main differences between dicotyledonous and monocotyledonous plants is the branching pattern of their stems. Dicotyledonous plants have stems that do not branch, while monocotyledonous plants have stems that branch.

The correct answer is "epidermis." The explanation for this is that the question is asking about the location of hair or root fibers, which are found in the epidermis. The epidermis is the outermost layer of cells in plants and animals, and it serves as a protective barrier. In the context of hair or root fibers, the epidermis is where the cells differentiate and form these structures.

The correct answer is "palisade, berperan dalam fotosintesis." The image shows a tissue structure in a leaf, which is referred to as the palisade tissue. This tissue is responsible for photosynthesis, the process by which plants convert sunlight into energy. It contains chloroplasts, which are the site of photosynthesis, and is located near the upper surface of the leaf to maximize exposure to sunlight.

The correct answer suggests that when the leaf is not covered, it turns dark blue after being tested with lugol. This implies that the lugol solution reacts with a specific substance in the leaf, resulting in a dark blue color.

Fotosintesis adalah proses di mana tumbuhan menggunakan energi matahari, air, dan karbon dioksida untuk menghasilkan glukosa dan oksigen. Proses ini terjadi di dalam kloroplas, organel yang mengandung pigmen hijau bernama klorofil. Klorofil bertanggung jawab untuk menyerap energi matahari yang diperlukan dalam fotosintesis. Oleh karena itu, jawaban yang benar adalah kloroplas.

Fototaksis adalah gerakan yang dilakukan oleh organisme dalam merespons cahaya. Pada hydrilla sp, gerakan kloroplas yang terjadi ketika terkena sinar matahari menunjukkan fototaksis, yaitu gerakan menuju atau menjauhi sumber cahaya.

The correct answer is "silinder pusat". In plants, the xylem and phloem are located in the central cylinder of the stem, which is also known as the central vascular bundle. This region contains the vascular tissues responsible for transporting water, nutrients, and sugars throughout the plant. The central cylinder is surrounded by the cortex, which provides support and protection to the vascular tissues. The endodermis is a layer of cells that surrounds the central cylinder, but it does not contain the xylem and phloem. Therefore, the correct answer is silinder pusat.

The correct answer is "bulir padi." This suggests that Hama walang sangit (a type of pest) is damaging the bulir padi (rice grain). The other options, daun (leaves), akar (roots), and batang (stem), do not directly relate to the damage caused by the pest. Therefore, the most logical explanation is that the pest is affecting the bulir padi.

The given answer states that the difference between dicotyledonous and monocotyledonous plants is that dicotyledonous plants have unbranched stems while monocotyledonous plants have branched stems. This is incorrect. The correct difference is that dicotyledonous plants have a taproot system, while monocotyledonous plants have a fibrous root system.

Osmosis is not a factor that causes water and minerals to move from the roots to the leaves. Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In the context of plant physiology, osmosis is involved in the movement of water into the roots from the soil, but it is not the main driving force for the upward movement of water and minerals through the xylem vessels. The main factors responsible for this upward movement are root pressure, capillary action in the xylem vessels, and transpiration pull created by the evaporation of water from the leaves.

The correct answer is "tekanan akar" because when the banana stem near the ground is pruned, water comes out in the pruning area. This indicates that the water is being pushed out by the pressure from the roots, which is known as "tekanan akar" in Indonesian.

The correct answer is "higroskopis". This is because the term "higroskopis" refers to the ability of a substance to absorb or release moisture from its surroundings. In the context of the question, the change in the water content of the fruit pod causes it to split open, indicating that it is higroskopis.

The correct answer is niktinasti. Niktinasti is the movement of plant parts in response to changes in the duration of light or darkness. In this case, the closing of the turi leaf is a response to the decreasing intensity of sunlight.

Geotropisme negatif adalah respons pada tumbuhan di mana tunas tumbuh menjauhi gravitasi bumi dan menuju ke arah yang berlawanan. Ini berarti tunas akan tumbuh ke atas, menjauhi tanah. Oleh karena itu, pertumbuhan tunas adalah jawaban yang tepat untuk pertanyaan ini.

The process of transpiration in plants involves the loss of water from the leaves through evaporation. As water evaporates from the surface of the leaves, it creates a negative pressure or tension that pulls water up from the roots through the xylem vessels. This process is known as the transpiration pull. Therefore, the statement "air di daun menguap sehingga daun mengambil air di pembuluh" accurately describes the process of transpiration and how water is transported from the roots to the leaves in plants.
