Practice question
Question
Consider the following changes during the maturation of a plant cell:
I. The capacity of the primary wall for growth diminishes.
II. A secondary wall forms towards the plasma membrane.
III. Cytoplasmic connections with neighbouring cells may still pass through the walls.
Which option correctly evaluates these statements?
Explanation
The primary wall grows in a young cell, but this capacity diminishes with maturity. The secondary wall is deposited on the inner side, towards the plasma membrane. Plasmodesmata may traverse the walls and connect neighbouring cytoplasms.
