Features of Meristem

Q. Meristematic cells have

1. thick cell wall and large intercellular spaces
2. thick cell wall and no intercellular spaces
3. thin cell wall and large intercellular spaces
4. thin cell wall and no intercellular spaces

Q.

Meristematic tissue needs a constant supply of nutrient to keep growing. Why?

1. It is a fast growing cell type and hence needs more energy

2. It cannot store nutrients due to constant cell division

3. The cells lack vacuoles to store nutrients

4. They are present at the growing ends of the plant

Q.

Cells of meristematic tissue lack vacuoles

1. True

2. False

Q. Match List I(Type of Tissues/structures) with List II(Characteristic features of the tissue) and select the correct answer using the codes given the lists.

c. Periblem	$3$. Occur on leaf tips responsible for guttation
d. Tyloses	$4$. Meristematic tissue responsible for the development of cortex
