Insektisida adalah cara yang tepat untuk mengatasi hama tanaman berupa serangga. Insektisida adalah bahan kimia yang dirancang khusus untuk membunuh atau mengendalikan serangga yang merusak tanaman. Dengan menyemprotkan tanaman menggunakan insektisida, serangga pengganggu dapat dieliminasi atau dikendalikan, sehingga tanaman dapat tumbuh dengan baik dan terhindar dari kerusakan yang disebabkan oleh hama.

The correct answer is stomata dan lentisel. Stomata are small openings on the surface of plant leaves and stems that allow for the exchange of gases, including the intake of carbon dioxide and the release of oxygen. Lentisel, on the other hand, are small pores or openings found on the surface of woody plants that allow for the exchange of gases in the bark. Together, stomata and lentisel facilitate the entry and exit of respiratory air in plants.

The correct answer is 3 and 5. This means that the parts indicated by numbers 3 and 5 are the ones that function as transport networks. Unfortunately, without the image or more context, it is difficult to provide a specific explanation for why these parts are considered transport networks.

The statement "gerak batang dan daun yang mengarah pada datangnya cahaya" describes positive phototropism, which is the movement of plants towards a source of light. This response is correct because positive phototropism involves the growth of stems and leaves towards the direction of incoming light.

CVPD (Citrus Vein Phloem Degeneration) is a disease that causes damage to the sieve tubes in citrus plants. This disease is caused by a complex of multiple pathogens, including viruses and bacteria. It leads to the degeneration of the phloem tissue, which affects the transport of nutrients and water within the plant. As a result, the affected citrus plants show symptoms such as vein clearing, leaf yellowing, and stunted growth. Therefore, CVPD is the correct answer for the question.

Photosynthesis is the process by which plants convert light energy into chemical energy. This chemical energy is stored in the form of glucose, which is used by the plant for growth and other metabolic activities. During photosynthesis, chlorophyll in the plant's cells absorbs light energy and converts it into chemical energy through a series of chemical reactions. This chemical energy is essential for the survival of plants and also serves as a source of energy for other organisms in the food chain.

Floem adalah jaringan yang berfungsi mengangkut hasil fotosintesis dari daun ke seluruh bagian tumbuhan. Floem terdiri dari sel-sel hidup yang disusun secara berkelompok membentuk pembuluh floem. Sel-sel dalam floem memiliki dinding sel yang tipis sehingga memungkinkan transportasi zat-zat organik seperti gula, asam amino, dan hormon ke seluruh tumbuhan. Dengan demikian, floem merupakan jaringan yang penting dalam proses pergerakan dan distribusi hasil fotosintesis dalam tumbuhan.

The correct answer is A because it states that there is cambium present in dicot plants, while there is no cambium in monocot plants. Cambium is a type of meristem tissue that is responsible for secondary growth in plants, which allows for the development of woody tissues such as xylem and phloem. This key difference in tissue composition is one of the main distinguishing factors between dicot and monocot plants.

Lingkaran tahunan adalah garis-garis yang menunjukkan hasil kegiatan dari suatu masa pertumbuhan pada pohon. Lingkaran tahunan terbentuk oleh pertumbuhan xilem yang berbeda pada musim panas dan musim dingin. Pada musim panas, xilem akan tumbuh dengan cepat dan membentuk kayu yang berpori besar, sedangkan pada musim dingin, pertumbuhan xilem melambat dan membentuk kayu yang berpori kecil. Dengan menghitung jumlah lingkaran tahunan pada batang pohon, umur pohon dapat ditentukan.

Kambium adalah jaringan yang berfungsi keluar membentuk kulit dan kedalam membentuk kayu. Kambium adalah lapisan sel yang terdapat di antara kulit kayu dan kayu yang aktif dalam pertumbuhan sekunder tumbuhan. Jaringan ini menghasilkan sel-sel baru yang membentuk lapisan kulit dan kayu yang bertambah tebal seiring dengan pertumbuhan tumbuhan.

Kaliptra berfungsi sebagai pelindung akar. Kaliptra adalah lapisan tipis yang melindungi ujung akar dari kerusakan fisik dan infeksi. Lapisan ini membantu melindungi akar saat tumbuhan sedang tumbuh melalui tanah dan menghindari cedera. Dengan melindungi akar, kaliptra memastikan bahwa akar dapat terus tumbuh dengan baik dan menyerap nutrisi yang diperlukan untuk pertumbuhan tumbuhan.

The correct answer is "Menutupnya daun puteri malu setelah disentuh." This is because the question asks for an example of thigmonastic movement in plants, and the closing of the leaves of the Mimosa pudica (puteri malu) after being touched is a well-known example of thigmonasty. Thigmonasty is a type of nastic movement in response to touch or physical contact.

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) using energy from sunlight. This equation follows the balanced stoichiometry of the reactants and products, with 6 molecules of CO2 and 6 molecules of H2O producing 1 molecule of C6H12O6 and 6 molecules of O2.

The correct answer is "melarutkan butiran khlorofil." In Sach's experiment, boiling the sample in alcohol is done to dissolve the chlorophyll granules present in the sample. This process helps in extracting and isolating chlorophyll for further analysis or study.

The correct answer is fotonasti. Fotonasti is a type of movement in plants that is triggered by light. In this case, the flower of the Mirabilis jalapa plant only blooms at 4 pm, which suggests that its blooming is influenced by light. Therefore, the movement of the flower opening at a specific time in response to light is an example of fotonasti.

An organism is said to be autotrophic if it is capable of converting inorganic substances into organic substances. Autotrophs are able to produce their own food using energy from sunlight or inorganic chemicals. They do not rely on consuming other organisms for their nutritional needs. This process is known as photosynthesis, where autotrophs use sunlight to convert carbon dioxide and water into glucose and oxygen. Autotrophs play a crucial role in the food chain by providing energy for heterotrophs, which are organisms that cannot produce their own food.

Fototaksis adalah gerakan yang dilakukan oleh organisme hidup sebagai respons terhadap cahaya. Ketika kloroplas pada hydrilla terkena sinar matahari, mereka akan bergerak menuju atau menjauhi sumber cahaya tersebut. Hal ini menunjukkan adanya fototaksis pada hydrilla, di mana mereka merespons sinar matahari dengan menggerakkan kloroplas mereka.

The correct answer is "Palisade dan bunga karang." This is because chlorophyll, which is responsible for the green color in leaves, is primarily found in the palisade layer of the leaf. The palisade layer is located just below the upper epidermis and contains densely packed chloroplasts, where photosynthesis takes place. The bunga karang, or coral-like structures, are not directly related to the presence of chlorophyll in leaves.

The correct answer is epidermis. The explanation is that hair or root fibers are only found in the young root region, which is a projection or differentiation of the epidermis tissue.

The correct answer is "air dan garam-garam mineral diangkut dari akar ke daun melalui pembuluh xilem". This is because xylem is responsible for transporting water and minerals from the roots to the leaves of a plant. The xylem vessels are specialized structures that allow for the upward movement of water and minerals through capillary action and transpiration pull. This process is essential for the plant's survival as it provides the necessary nutrients and water for photosynthesis and other metabolic processes.

Haptonasti is the correct answer because it refers to the movement of plants in response to touch or contact. In the case of the Venus flytrap, when an insect enters the trap and touches the trigger hairs, the plant responds by rapidly closing its leaves to trap the insect. This movement is a result of the plant's ability to detect and respond to physical stimuli, which is characteristic of haptonasti.

The correct answer is "higroskopis." Higroskopis refers to the ability of a substance to absorb moisture from its surroundings. In the context of the question, the bursting of the fruit pods of legumes is due to a change in the water content of the pods. As the water content increases, the pods expand and eventually burst open, dispersing the seeds. This process is known as higroskopis.

The correct answer is "silender pusat." Xylem and phloem are found in the central cylinder of the stem, which is also known as the vascular bundle. The central cylinder is responsible for transporting water, nutrients, and sugars throughout the plant.

The structure X in the given anatomical root diagram is the root hairs. Root hairs are responsible for increasing the surface area of the root, which helps in the absorption of water and nutrients from the soil. Therefore, the function of structure X is to expand the area for the absorption of water and nutrients from the soil.

The experiment in the picture is likely demonstrating the production of oxygen during photosynthesis. This can be inferred because the bubbles being produced in the test tube are likely oxygen gas, which is a byproduct of photosynthesis.

The given statement mentions that the tendrils of the passion fruit grow by coiling around objects. This type of movement is known as tigmotropism. Tigmotropism is a directional growth movement in response to physical contact or mechanical stimulation. In this case, the tendrils of the passion fruit plant exhibit tigmotropism by coiling around objects for support and climbing.

Fotosintesis adalah proses di mana tumbuhan menggunakan energi matahari untuk mengubah air dan karbon dioksida menjadi glukosa dan oksigen. Proses ini terjadi di dalam kloroplas, yaitu organel yang terdapat di dalam sel tumbuhan. Kloroplas mengandung pigmen hijau bernama klorofil yang bertanggung jawab dalam menangkap energi matahari untuk digunakan dalam fotosintesis. Oleh karena itu, kloroplas adalah tempat terjadinya proses fotosintesis.

Niktinasti adalah gerakan tumbuhan yang dipengaruhi oleh perubahan intensitas cahaya. Ketika intensitas cahaya matahari berkurang, daun turi akan menutup untuk mengurangi paparan langsung terhadap cahaya. Hal ini dapat membantu melindungi daun dari kerusakan akibat sinar matahari yang terlalu terang. Oleh karena itu, niktinasti adalah penjelasan yang tepat untuk gerakan menutupnya daun turi dalam kondisi berkurangnya intensitas cahaya matahari.

Dikotil batang tidak bercabang, sedangkan monokotil bercabang. Dikotil memiliki batang yang tidak bercabang, biasanya dengan pertumbuhan primer yang terbatas. Monokotil, di sisi lain, memiliki batang yang bercabang, yang memungkinkan pertumbuhan sekunder yang terus menerus. Ini adalah perbedaan utama antara tumbuhan dikotil dan monokotil dalam hal struktur batang mereka.

Geotropisme negatif adalah respons tumbuhan terhadap gravitasi yang menyebabkan pertumbuhan tunas ke atas, menjauhi arah gravitasi. Ini berarti tunas tumbuhan cenderung tumbuh ke atas, menjauhi tanah.

Based on the given information, when the leaf is tested with lugol, the part of the leaf that is not covered will turn dark blue. This suggests that the correct answer is "tidak ditutup berwarna biru tua" which means "not covered is dark blue" in English.

Osmosis is not a factor that causes water and minerals to move from roots to leaves. Osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane. In the context of plant physiology, osmosis primarily occurs in the movement of water from the soil into the root cells. However, the main factors that contribute to the upward movement of water and minerals from roots to leaves are the transpiration pull created by the evaporation of water from the leaf surface (daya hisap daun), the capillary action of xylem vessels (sifat kapilaritas pembuluh kayu), and the root pressure (tekanan akar).

The correct answer is "tekanan akar" (root pressure). This is 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 exerted by the roots.

Daya isap daun adalah salah satu proses untuk mengangkut air dari akar ke daun, yang dapat terjadi karena air di daun menguap sehingga daun mengambil air di pembuluh. Ketika air di daun menguap melalui stomata, tekanan negatif terbentuk di dalam daun. Tekanan negatif ini menyebabkan air di pembuluh xilem pada akar ditarik ke atas menuju daun. Proses ini dikenal sebagai daya isap daun.
