MCQ

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?

Options

Choose one · Correct answer highlighted

Only statement I is correct. Only statements I and II are correct. Only statements II and III are correct. Statements I, II and III are correct. Correct

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.
