Unit 4: Cell Growth and Reproduction

Asexual reproduction requires

• Two parents

• Only one parent

Which organism reproduces asexually??

• bunny

• shark

• sea star

• rose plant

What process is shown and what kind of cells result??

• Mitosis: sex cells

• Mitosis: cells with variation

• Meiosis: body cells

• Meiosis: cells with variation

Which explanation best describes meiosis??

• daughter cells are genetically identical to parent cells

• Meiosis does not occur in sex cells

• Daughter cells produced contain half the number of chromosomes of the parent

• Cells in meiosis only divide once.

What difference is there in the reproduction of body cells and sex cells??

• There is no difference. Both divide by meiosis.

• There is no difference. Both divide by mitosis.

• Body cells divide by mitosis and sex cells divide by meiosis.

• Body cells divide by meiosis and sex cells divide by mitosis.

What is an advantage of sexual reproduction??

• Offspring are born live instead of hatch from eggs.

• Offspring are resistant to all viruses.

• Offspring have genetic variety.

• Offspring are directly identical to the parents.

In sexual reproduction, a sperm unites with an egg to fertilize it, further developing into a new organism.

Which of the descriptions best explains how offspring inherit genetic information form their parents??

• Offspring gets all of the genes from their mom.

• Offspring gets half of the genes from each parent.

• Offspring gets more genes from mom than dad.

• Offspring gets more genes from dad than mom.

A frog cell has 26 chromosomes. How many chromosomes would you expect to find in the daughter cells produced by meiosis??

• 13

• 52

• 26

• 44

These can be inheirited or acquired.

The two ways cells can reproduce are ____ and ____.
