Unit 2 Review

What is the cell cycle?

• The process of cell division

• The growth and replication of cells

• The regulation of cell functions

• The formation of body tissues

Why do cancer cells divide too frequently?

• Genetic factors

• Exposure to toxins

• Excessive exposure to UV light

• All of the above

What can happen if cancer cells are not regulated?

• They can communicate with healthy cells

• They can carry out normal cell functions

• They can anchor themselves securely

• All of the above

What is the role of mitosis in cell reproduction?

• To split the cytoplasm

• To make new body cells

• To regulate cell functions

• To make sex cells

Why is the cell cycle regulated?

• To prevent uncontrolled cell division

• To ensure cells are growing well

• To replicate DNA correctly

• All of the above
