Question

plant cells typically achieve cytokinesis by:
multiple choice
○ chromosome condensation.
○ chromosome elongation.
○ forming a cleavage furrow that pinches the cell into two.
○ binary fission.
○ forming a cell plate across the middle of the cell.

Explanation:

Cytokinesis is the division of the cytoplasm after mitosis. Plant cells have rigid cell walls, so they cannot form a cleavage furrow (animal cell method). Instead, vesicles from the Golgi apparatus fuse at the cell's equator to form a cell plate, which develops into a new cell wall separating the two daughter cells. Chromosome condensation/elongation are mitotic steps, not cytokinesis; binary fission is for prokaryotes.

Answer:

forming a cell plate across the middle of the cell.
