The period of growth is generally divided into three phases, namely, meristematic, elongation and maturation.
Identify the regions on the basis of following features:
A. Cells increase in number and so does the size of vacuoles and new cell wall deposition.
B. Cells are rich in protoplasm, large conspicuous nucleus, thin cellulosic cell wall with plasmodesmata connections.
C. Cells attain their maximum sizes in terms of wall thickening and protoplasmic modification.
Cells have dense protoplasm, conspicuous nucleus, thin cell wall with plasmodesmata and cells go on dividing- Meristematic phase.
New cell wall depositions, increase in size of vacuole and cell enlargement - Elongation phase
Cells attain their maximum size, complete the protoplasmic modifications, Complete cell wall thickening - Maturation phase.
