Unit 3 Chapter 13 Mitosis

Why do cells reproduce?

• To maintain the size of the organism and to allow the organism to remain the same

• To maintain the stability of the organism and to allow the organism to grow

• To produce energy

• To eliminate waste

What is the cell cycle?

• A process of cell death

• A series of events that cells go through as they grow and divide

• A method of energy production

• A type of cell communication

What happens during the S phase of interphase?

• Cell division

• The chromatin and centrosomes are copies

• Protein synthesis

• Cell death

What is the function of centrosomes?

• To store nutrients

• To organize microtubules and provide structure for the cell

• To produce energy

• To transport waste

Why is it important that each daughter cell have the same genetic material?

• To ensure genetic diversity

• To maintain the species' characteristics

• To increase mutation rates

• To promote cell death

What is the function of spindle fibers?

• To transport nutrients

• To pull apart sister chromatids

• To produce energy

• To store genetic information

What do chromosomes do in metaphase?

• They replicate

• They align in the center of the cell

• They disassemble

• They produce proteins

In which phase does the cell begin to stretch?

• Prophase

• Metaphase

• Anaphase

• Telophase

In which phase do spindle fibers disassemble?

• Prophase
