In the G1 stage of the cell cycle, the cell

• Grows
• Matures
• Carries on normal activities
• All of the above

The cell spends most of it's life in ________________.

• mitosis
• cytokinesis
• Interphase
• None of the above

In the S stage of interphase_______________

• the cell grows
• the nucleus divides
• the cell membrane divides
• the DNA is replicated

When a plant cell goes through cell division,  _____________.

• the 2 new nuclei are separated by the cell membrane pinching off.
• 4 new cells are formed
• a cell plate forms, dividing the 2 new nuclei
• None of the above
