Question

1. Comment on the following statement.

One of the characteristic features of plant cell is the presence of vacuoles. But vacuoles are absent in meristematic cells.

Answer 1

Meristematic cells:

1. Vacuoles are cell organelles used to store waste materials, store nutrients and excess salts, etc.
2. They are usually larger in size and more in number in matured cells.
3. Meristematic cells need dense cytoplasm and thin cell walls.
4. Meristematic cells have immense potential to divide.
5. For this purpose, they have dense cytoplasm and thin cell walls.
6. Due to this reason, meristematic cells lack vacuole.
7. Meristematic cells are undifferentiated and constantly diving into immature cells.
8. Also as they do not have any waste material to store, vacuoles are absent.
