Solution
The correct option is A Intussusception
Intussusception is the growth of the cell wall by the deposition of cellulose. The plant cell wall is a product of protoplasmic activity and in the higher plants its development begins with the formation of the cell plate, immediately after nuclear division. This thin cell plate quickly acquires the form of a primary cell wall, which is defined as the structure which encloses the protoplasts during the period of cell enlargement. Once, the period of cell enlargement is over the cell wall becomes thickened to become the secondary wall. The secondary wall is regarded as the structural component of the plant.
