Bio Chapter 10 Cell Growth and Division

Which event occurs during interphase?

• cytoplasm divides
• DNA replicates
• spindle fibers form
• centromeres divide

If cells are removed from tissue, then new cells later fill in that space and stop dividing, it's an example of

• random cell mutations

• physical cell-to-cell contact inhibition

• carcinogenic exposure

• surface area: volume ratio rule

Compared to small cells, large cells have more trouble

• dividing
• producing daughter cells
• storing needed materials and waste products
• moving needed materials in and waste products out

Which of the following explains why normal cells covering a petri dish tend to stop dividing?

• the cells lack cyclin
• the petri dish inhibits growth
• contact with other cells stops cell growth
• most cells grown in petri dishes have a defective p53 gene

What is the correct structure and function of letter B in the diagram?

• centrioles - make spindles
• spindle fibers - help divide chromosomes
• centromere - hold chromatids together
• chromosome - hold DNA/genes
