Q.

Meristems are cells that -------------------------

1. Store food

2. Help in excretion

3. Provide support

4. Divide continuously to produce new cells

Q. Meristamatic tissue or permanent tissues are different but they formed by meristamatic tissues what is the relations between them I confused or when the plant is mature we say meristamatic tissue turn into permanent tissues
can I find both of them in mature plant
