Question

what happens during cytokinesis? the chromosomes line up in the middle of the cell. the cytoplasm divides, and the two daughter cells separate. the chromosomes condense, and the nuclear membrane disappears. the cell grows, replicates its dna, and gets ready to divide.

Explanation:

To solve this, we analyze each option based on the definition of cytokinesis:

• Option 1: Chromosomes lining up in the middle is metaphase (mitosis), not cytokinesis.
• Option 2: Cytokinesis is the process where the cytoplasm divides, resulting in two separate daughter cells. This matches the definition.
• Option 3: Chromosome condensation and nuclear membrane disappearance occur in prophase (mitosis), not cytokinesis.
• Option 4: Cell growth, DNA replication, and preparation for division are part of interphase, not cytokinesis.

Answer:

The cytoplasm divides, and the two daughter cells separate.
