Lingkaran tahunan adalah garis-garis yang menunjukkan hasil kegiatan dari suatu masa pertumbuhan pohon. Lingkaran tahunan terbentuk oleh lapisan-lapisan kayu yang bertambah setiap tahunnya. Dengan menghitung jumlah lingkaran tahunan pada batang pohon, kita dapat memperkirakan umur pohon tersebut.

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 phloem tissue, which is responsible for transporting sugars and nutrients throughout the plant. The damage to the sieve tubes can result in stunted growth, yellowing of leaves, and reduced fruit quality. Therefore, CVPD is the correct answer as it is the disease that specifically causes damage to the sieve tubes in citrus plants.

The correct answer is "insektisida". Insektisida is the appropriate way to deal with plant pests in the form of insects. Insektisida is a type of pesticide specifically designed to kill or control insects that can damage plants. It is commonly used in agriculture to protect crops from insect infestation and minimize crop losses. By spraying plants with insektisida, it helps to eliminate or reduce the population of harmful insects, thereby protecting the plants and promoting healthy growth.

Kambium adalah jaringan yang berfungsi keluar membentuk kulit dan kedalam membentuk kayu. Kambium terletak di antara xilem dan floem pada batang tumbuhan. Jaringan ini bertanggung jawab untuk pertumbuhan sekunder pada tumbuhan, yang melibatkan pembentukan lapisan baru dari xilem dan floem. Kambium menghasilkan sel-sel baru yang membentuk kayu di bagian dalam batang dan sel-sel baru yang membentuk kulit di bagian luar batang. Dengan demikian, kambium adalah jawaban yang tepat untuk pertanyaan ini.

The correct answer is "menghasilkan oksigen". This is because the experiment shown in the picture aims to prove that photosynthesis produces oxygen.

The correct answer is fotonasti. Fotonasti refers to the movement or response of a plant to light stimulus. In this case, the flower of the Mirabis jalappa plant only blooms at 4 PM, indicating that it is responding to the specific light conditions at that time. This movement is not triggered by touch (tigmotropisme) or a specific direction of light (fototropisme), but rather by the presence or absence of light (fotonasti).

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

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 on the surface of woody stems that allow for the exchange of gases, as well as the intake of oxygen and the release of carbon dioxide. Therefore, both stomata and lentisel play a role in the process of respiration in plants by facilitating the entry and exit of air.

The correct answer is 3 and 5. From the given image, it can be observed that the parts labeled as 3 and 5 are the ones that function as the transport network. The other options do not show any indication of being involved in the transportation process.

The correct answer is "floem" because floem is the tissue responsible for transporting the products of photosynthesis, such as sugars and organic compounds, from the leaves where they are produced to other parts of the plant. Parenchyma is a type of plant tissue that has various functions, but it is not specifically involved in the transport of photosynthetic products. Xylem is responsible for transporting water and minerals, while epidermis is the outermost layer of cells in plants.

The correct answer is A because the difference between dicot plants and monocot plants is that dicot plants have cambium, while monocot plants do not have cambium.

The correct answer is "Menutupnya daun puteri malu setelah disentuh." This is because the question asks for an example of tigmomovement in plants, and the closing of the leaves of the sensitive plant (puteri malu) after being touched is a well-known example of tigmomovement. Tigmomovement refers to the movement or response of a plant to touch or contact stimuli.

The correct answer is tigmotropisme. Tigmotropisme refers to the directional growth of a plant in response to touch or physical contact. In this case, the sulur pada markisa (passionfruit tendrils) grow by wrapping around a support, which is a response to physical contact. This is a form of tigmotropism.

Kaliptra berfungsi sebagai pelindung akar. Kaliptra adalah lapisan tipis yang melindungi ujung akar saat akar sedang tumbuh. Lapisan ini melindungi akar dari kerusakan fisik dan infeksi oleh patogen. Dengan demikian, kaliptra membantu menjaga keberlanjutan pertumbuhan akar dan melindungi akar dari kerusakan eksternal.

The correct answer is "air dan garam-garam mineral diangkut dari akar ke daun melalui pembuluh xilem". This is because the xylem is responsible for the transport of water and minerals from the roots to the leaves in a plant. The xylem vessels form a continuous network throughout the plant, allowing for the upward movement of water and minerals against gravity. This process is known as transpiration and is essential for the plant's survival and growth.

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

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 explains that the movement of the stem and leaves is directed towards the incoming light, indicating that the plant is exhibiting a positive response to light.

Fototaksis adalah gerakan yang dilakukan oleh organisme hidup sebagai respons terhadap cahaya. Gerak kloroplas pada hydrilla sp yang terkena sinar matahari menunjukkan fototaksis, yaitu gerakan kloroplas menuju cahaya untuk melakukan fotosintesis.

Based on the given anatomical structure of the root, the function of structure X is to expand the area of water and nutrient absorption from the soil.

The correct answer is "higroskopis". Higroskopis refers to the ability of a substance to absorb moisture from the air, causing it to expand and eventually break apart. In the context of the question, the bursting of the fruit pod is caused by a change in moisture content, which is a characteristic of higroskopis.

An organism is considered autotrophic when it is capable of converting inorganic substances into organic substances. Autotrophs are able to produce their own food through processes such as photosynthesis or chemosynthesis, using energy from the sun or certain chemicals respectively. This ability to convert inorganic substances into organic substances is a defining characteristic of autotrophs, allowing them to sustain themselves without relying on other organisms for food.

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, it triggers a rapid closure of the trap. This movement is a form of haptonasti, as it is a response to physical contact.

The correct answer is kloroplas. Photosynthesis is the process by which plants convert sunlight into energy, and it occurs in the chloroplasts of plant cells. Chloroplasts contain a pigment called chlorophyll, which captures the energy from sunlight and uses it to produce glucose. Therefore, the correct answer is kloroplas.

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 sunlight energy. This equation accurately shows the balanced reaction and the products formed during photosynthesis.

The correct answer is Palisade dan bunga karang. The explanation for this answer is that chlorophyll, which gives leaves their green color and is responsible for photosynthesis, is mainly found in the palisade layer of the leaf. The palisade layer is located just below the upper epidermis and contains densely packed chloroplasts. Additionally, bunga karang (coral) is not related to the presence of chlorophyll in leaves, so it is not a relevant option in this context.

The correct answer is "melarutkan butiran khlorofil" (to dissolve chlorophyll granules). In this experiment, boiling the sample in alcohol helps to break down the cell membranes and release the chlorophyll from the cells. This allows the chlorophyll to dissolve in the alcohol, making it easier to extract and analyze.

The correct answer is "silender pusat." Xylem and phloem are tissues that are responsible for transporting water, nutrients, and sugars throughout the plant. These tissues are found in the central cylinder of the stem, which is also known as the central vascular bundle or the pith. The central cylinder is located in the center of the stem and is surrounded by other tissues such as the cortex and the endodermis.

Air dan mineral dapat naik dari akar ke daun melalui daya hisap daun, sifat kapilaritas pembuluh kayu, dan tekanan akar. Osmosis, di sisi lain, adalah pergerakan air melalui membran semipermeabel dari daerah dengan konsentrasi air yang lebih rendah ke daerah dengan konsentrasi air yang lebih tinggi. Osmosis tidak terkait dengan pergerakan air dan mineral dari akar ke daun.

Niktinasti is the correct answer because it refers to the movement of plant parts in response to changes in light intensity. In this case, the closing of the turi leaf is a response to the reduced intensity of sunlight.

The correct answer is "tekanan akar" (root pressure). When a banana stem near the ground is pruned, water is released in the pruning area. This indicates that the water is being pushed out by the root pressure.

Geotropisme negatif adalah respons pada tumbuhan di mana tunas tumbuh ke atas, menjauhi gravitasi bumi. Ini berarti bahwa tunas tumbuh menjauh dari tanah dan menuju cahaya. Ini adalah respon yang penting bagi tumbuhan karena memungkinkan tunas untuk mencapai sinar matahari yang penting untuk fotosintesis dan pertumbuhan yang sehat.

The correct answer is "dikotil batang tidak bercabang, monokotil bercabang". This is because the main difference between dicotyledonous and monocotyledonous plants is the branching pattern of their stems. Dicotyledonous plants have a branched stem, while monocotyledonous plants have an unbranched stem. All the other options listed in the question are correct in describing the differences between dicotyledonous and monocotyledonous plants.

The correct answer is "tidak ditutup berwarna biru tua". This means that when the leaf is tested with iodine, the part of the leaf that is not covered will turn dark blue.

Daya isap daun adalah salah satu proses untuk mengangkut air dari akar ke daun. Air di daun menguap sehingga daun mengambil air di pembuluh. Ketika air di daun menguap melalui stomata, terjadi perbedaan tekanan antara daun dan akar. Ini menciptakan gradien tekanan yang memungkinkan air untuk naik dari akar ke daun melalui pembuluh xilem. Jadi, air di daun menguap adalah faktor utama yang memungkinkan terjadinya daya isap daun.
