Cell Cycle Test Study Guide

List the most common limiting factors for cell growth

• cancer

• surface area to volume ratio

• gender

• whether the cell is big enough or not

What are the 3 main reasons cells divide?

• Repair

• Growth

• Protect

• Replacement

Describe this phase of Mitosis:

Prophase

• nucleus reforms with the chromosomes; cell gets ready to divide

• The nucleus disappears, and spindle fibers form

• Spindle fibers attack the chromatids and line up in the middle

• Spindle fibers pull chromatids apart

Describe this phase of Mitosis:

Metaphase

• nucleus reforms with the chromosomes; cell gets ready to divide

• The nucleus disappears, and spindle fibers form

• Spindle fibers attack the chromatids and line up in the middle

• Spindle fibers pull chromatids apart

Describe this phase of Mitosis:

Anaphase

• nucleus reforms with the chromosomes; cell gets ready to divide

• The nucleus disappears, and spindle fibers form

• Spindle fibers attack the chromatids and line up in the middle

• Spindle fibers pull chromatids apart

Describe this phase of Mitosis:

Telophase

• nucleus reforms with the chromosomes; cell gets ready to divide

• The nucleus disappears, and spindle fibers form

• Spindle fibers attack the chromatids and line up in the middle

• Spindle fibers pull chromatids apart
