Bio U3 Review (TEST)

What happens during cytokinesis?

• The cell grows

• Chromosomes are duplicated.

• The nucleus divides.

• The cytoplasm and cell membrane split, forming daughter cells.

During which stage of interphase does DNA replicate?

• Mitosis

• Growth 1

• Growth 2

• Synthesis

Why is interphase the longest stage of the cell cycle?

• the nucleus takes numerous days to divide

• gametes are produced over a long period of time

• the cytoplasm and cell membrane separate after telophase

• the cell grows in size and replicates the DNA

What is the correct order of the phases of mitosis?

• Metaphase, Anaphase, Prophase, Telophase,

• Pelophase, Motophase, Anaphase, Trophase

• Prophase, Metaphase, Anaphase, Telophase

• Telophase, Anaphase, Prophase, Metaphase

Which best describes the purpose of sexual reproduction?
