Question

1. cytokinesis is defined as

a. reproductive cell division.
b. cytoplasmic division.
c. stage of cell division when replication of dna occurs.
d. somatic cell division.

Explanation:

To solve this, we analyze each option:

• Option a: Reproductive cell division is meiosis, not cytokinesis.
• Option b: Cytokinesis is the process of cytoplasmic division that occurs after nuclear division (mitosis or meiosis) in cell division.
• Option c: DNA replication occurs during the S - phase of the cell cycle, not during cytokinesis.
• Option d: Somatic cell division is mitosis, and cytokinesis is a part of mitosis (and meiosis) but is specifically the cytoplasmic division, not the entire somatic cell division process.

Answer:

b. Cytoplasmic division.
