Cell Division: Mitosis and Meiosis Quiz

What is the main purpose of mitosis in a human body?

• To create sex cells like sperm and eggs

• To allow for growth and to repair damaged tissue

• To reduce the number of chromosomes by half

• To make cells that are genetically unique

Which of the following is a process that is performed by both mitosis and meiosis?

• Producing four cells

• Making cells for sexual reproduction

• Starting with a single parent cell

• Cutting the chromosome number in half

The process of meiosis is essential for sexual reproduction because it:

• Repairs damaged tissue in the body

• Makes new cells that are identical to the parent cell

• Creates four haploid cells (gametes) that can join to form a new diploid

• Doubles the chromosome number in the cell

During meiosis, what is the name of the process where homologous chromosomes pair up and trade segments?

• Replication

• Crossing over

• Cytokinesis

• Mutation

The structure labeled 1 in the image is a ​ (a)   and the structure labeled 2 ia a ​ (b)   ​

• centriole
• spindle fiber
• chromosome
• sister chromatid
• chromatin
• nucleus
