Question

1.(a) Define meristematic tissue.
(b) Draw a diagram that shows the location of the meristematic tissues in a plant body.
(c) Mention the function of the different types of meristematic tissues.
(d) Why do meristematic cells lack vacuoles?

Answer 1

1. Answer:

The meristem is a type of tissue found in plants. It consists of undifferentiated cells capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide.

4. Answer : Meristematic cells are the cells that divide frequently. These cells need dense cytoplasm and thin cell walls. Meristematic cells have immense potential to divide. For this purpose, they have dense cytoplasm and thin cell walls. Due to this reason, meristematic cells lack vacuole.
