Question

Cells attaining their maximum size in terms of wall thickening and protoplasmic modifications belong to

• A. Meristematic phase
• B. Elongation phase
• C. Maturation phase
• D. None of the above

Answer 1

Answer: (C)

Maturation phase

There are three phases of growth, namely meristematic, elongation and maturation phase. In meristematic phase, the cells divide continuously. In this, the cells have the primary cell wall which is thin and cellulosic. In elongation phase, cell enlargement takes place. New cell wall deposition occurs in this phase. During maturation phase, cells attain maximum size in terms of wall thickening and protoplasmic modifications.

Thus, the correct answer is option C.
