Structural characteristics of

a) Meristematic cells near the root tip:

• large nucleus

• rich protoplasm

• vacuoles are less in number

• cell wall is thin and made up of cellulose

• No intercellular spaces

This is an area of cell division.

b) The cells in the elongation zone of the root

• more number of vacuoles

• new cellulosic walls are deposited

• there is an increase in size

This is an area of cell elongation.
