• prophase, anaphase, metaphase and telophase.

• prophase, telophase, anaphase and metaphase.

What happens in prophase of mitosis?

• Crossing over

• Chromosome become shorter and thicker

• Separation of homologous chromatids

• Synapsis

How many daughter cells are produced at the end of mitosis?

• 2 cells

• 4 cells

• 6 cells

• 8 cells

The diagram shows a cell cycle.

What does P represent?

• Cytokinesis

• Mitosis

Cytokinesis in plant begins with the formation of

• cell wall on one side.

• ring from the sides.
