Correct Answer
E. A group of young cells which actively divideExplanation
Meristem tissue is a group of young cells which actively divide. This tissue is responsible for the growth and development of plants. The cells in meristem tissue are undifferentiated, meaning they have not yet specialized into specific cell types. Due to their ability to continuously divide, meristem cells give rise to new cells that can differentiate into various types of plant tissues, such as leaves, stems, and roots. Therefore, the correct answer is "A group of young cells which actively divide."Rate this question:

Proses pengeluaran tetes – tetes air melalui hidatoda pada daun disebut ...
- A.
Gutasi
- B.
Eliminasi
- C.
Transpirasi
- D.
Transportasi
- E.
Respirasi
Correct Answer
A. GutasiExplanation
Gutasi is the process of water droplets being released through the hydathodes on the leaves. This process occurs when the root pressure in the plant is higher than the atmospheric pressure, causing water to be forced out of the hydathodes. This is different from transpiration, which is the loss of water vapor through the stomata on the leaves. Gutasi is a mechanism for plants to release excess water and is often observed in the morning or during periods of high humidity.Rate this question:

- E.
Parenchyma
Correct Answer
E. ParenchymaExplanation
Parenchyma is a type of plant tissue that can be found in almost every part of the plant. It is responsible for various functions such as storage, photosynthesis, and secretion. Parenchyma cells have thin cell walls and large central vacuoles, allowing them to store water and nutrients. They also have the ability to divide and differentiate, making them versatile for different plant functions. Therefore, it is correct to say that parenchyma is a tissue that can be found in almost every part of the plant.Rate this question:

- D.
Rimpang merupakan modifikasi dari batang dan daun
- E.
Akar merupakan modifikasi dari batang
Correct Answer
E. Akar merupakan modifikasi dari batangExplanation
The correct answer is "Akar merupakan modifikasi dari batang." This statement is incorrect because roots are not modifications of stems. Roots and stems are two distinct plant organs with different functions. Roots primarily function to anchor the plant in the ground and absorb water and nutrients, while stems provide structural support and transport water, nutrients, and sugars throughout the plant.Rate this question:
