Question

Why do meristematic tissues lack vacuoles?

Answer 1

Hint: Meristematic tissues contain undifferentiated cells that serve as the foundation for specialized plant structures. Meristematic tissues contain living cells of various shapes. They have a large nucleus that is devoid of the vacuole. There is no intercellular space between the cells. Meristem is the location where these cells exist.

Complete answer:
Meristematic tissue cells divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, and so on. These cells contribute to the plant's length and girth.

Meristematic tissue has the following characteristics:
- Meristems are the cells that make up these tissues.
- Meristematic tissue is capable of self-renewal. When a cell divides, one cell remains identical to the parent cell while the others form specialized structures.
- They have a small number of vacuoles.
- The meristematic tissue is alive and has a thin wall.
- Cell protoplasm is extremely dense.
- A plant's wounds are healed by meristematic tissues.
- Meristematic tissue cells are immature and young.
- They do not keep food.

Meristematic cells are those that divide a lot. The dense cytoplasm and thin cell walls are required by these cells. Meristematic cells have a tremendous ability to divide. They have dense cytoplasm and a thin cell wall for this purpose. Meristematic cells, as a result, lack a vacuole.

Note: Apical dominance occurs when one meristem prevents or inhibits the growth of another. As a result, the plant will have a single, distinct main trunk. In trees, for example, the dominant shoot meristem is located at the tip of the main trunk. As a result, the trunk's tip grows quickly and is not shaded by branches. If the dominant meristem is severed, one or more branch tips will take over.
