Stomata and trichomes are modifications of the epidermis tissue. Stomata are small openings found on the surface of leaves and stems that allow for gas exchange, while trichomes are hair-like structures that can serve various functions such as reducing water loss or providing protection against herbivores. The epidermis is the outermost layer of cells in plants and is responsible for protecting the underlying tissues. Therefore, it makes sense that stomata and trichomes, which have specialized functions related to protection and gas exchange, would be modifications of the epidermis.

The correct answer is kelapa. The annual circle is a term used to describe the growth rings found in the trunk of a tree. However, coconut trees do not have visible annual growth rings in their trunks. Therefore, the coconut tree is the only plant mentioned that does not have an annual circle.

The correct answer is "totipotensi sel" because the principle of tissue culture is based on the assumption that every plant cell has the ability to regenerate into a complete plant. This property of cells is called totipotency, which means they have the potential to differentiate into any type of cell and regenerate into a whole organism.

The correct answer is 1-2-3. The question asks for the numbers that represent parenchyma tissue in plants. Parenchyma is a type of simple plant tissue that is involved in various functions such as photosynthesis, storage, and secretion. In the given options, numbers 1, 2, and 3 represent palisade, spongy, and cortex tissues, respectively, which are all types of parenchyma tissue.

The correct answer is 2 because it is commonly known that photosynthesis occurs in the chloroplasts of plant cells. The chloroplasts contain a green pigment called chlorophyll, which is responsible for capturing sunlight and converting it into energy through the process of photosynthesis. Therefore, the correct answer is 2 as it indicates the location where photosynthesis takes place.

Parenchyma is a type of tissue found in plants that consists of living cells with complete cell organelles. It is considered the fundamental tissue in plants because it is involved in various functions such as photosynthesis, storage, and secretion. Unlike other tissues mentioned in the options, parenchyma cells are alive and retain their organelles, making them the correct answer in this context.

Pertumbuhan dan perkembangan cambium vaskuler ke arah dalam pada batang akan menghasilkan xylem sekunder. Cambium vaskuler adalah lapisan meristem yang terletak di antara xylem dan floem pada batang. Pertumbuhan cambium vaskuler ke arah dalam menghasilkan xylem sekunder, yang terbentuk dari sel-sel xilem baru yang ditambahkan ke arah dalam. Xylem sekunder memiliki fungsi dalam mengangkut air dan nutrisi dari akar ke daun serta memberikan dukungan struktural pada tanaman.

Kolenkim adalah salah satu jaringan yang menyusun tangkai daun. Jaringan ini memiliki sifat yang elastis dan fleksibel, sehingga memungkinkannya untuk melentur saat terkena angin. Jaringan sklerenkim, parenkim, epidermis, dan xilem tidak memiliki sifat yang sama sehingga tidak dapat menjawab pertanyaan ini.

The correct answer is perikambium. Perikambium adalah jaringan meristem yang terdapat di antara xilem dan floem pada tumbuhan. Jaringan ini bertanggung jawab dalam pertumbuhan sekunder tumbuhan, yaitu pertumbuhan pada diameter batang dan akar. Akar yang muncul pada stek dapat berasal dari perikambium karena jaringan ini memiliki kemampuan untuk membelah diri dan menghasilkan sel-sel baru yang akan menjadi akar.
