Question

How does cytokinesis in plant cells primarily differ from that in animal cells?
Options
A Plant cells form a cleavage furrow, while animal cells build a cell plate.
B Plant cells develop a cell plate from Golgi-derived vesicles, while animal cells form a cleavage furrow.
Correct Answer
C Plant cells undergo binary fission, while animal cells use mitosis.
D Cytokinesis is absent in plant cells due to the rigid cell wall, unlike animal cells.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Section 8.9 explains: 'A distinctive feature of plant cytokinesis is the formation of a cell plate — a new partition built from Golgi-derived vesicles carrying cell wall materials — which develops outward from the centre of the dividing cell to form the new cell wall between daughter cells, since plant cells cannot divide by simple pinching (as animal cells do) owing to the rigid cell wall.' Animal cells form a cleavage furrow.

Hint

Consider the presence of a rigid cell wall in plants and how that would impact the physical division of the cytoplasm, unlike in animal cells.
