SPICY Mitosis and Meiosis Review

Which phase of the cell cycle is depicted in this image?

• Cytokinesis
• Interphase
• Anaphase
• Metaphase

Which of the following does not occur by mitosis?

• growth
• production of gametes
• repair
• development in the embryo

The cell membrane pinches in, dividing the cytoplasm into 2 cells

• Metaphase
• Anaphase
• Telophase
• Cytokinesis

Which best describes the process shown?

• mutation
• splitting of sister chromatids
• crossing-over in which  genetic material is exchanged

Which of the following best describes meiosis?

• It is carried out in all tissues that require cell replacement
• It occurs only in cells in the reproductive structures of an organism
• It happens in all of the tissues except the brain and spinal cord
• It is the first stage of mitosis

A male shark has 40 chromosomes in each of its sex cells(gametes). How many would be present in its body cells?

• 20
• 40
• 80
• 160

function of mitosis

• genetic diversity though sexual reproduction
• cell reproduction and general growth and repair

A guinea pig cell has 64 chromosomes.  After MITOSIS, each daughter contains ___ chromosomes.

• 128
• 64
• 32
• 16

Why is meiosis important for sexual reproduction? 

• It allows  cells to have triple the chromosome number of the organism. 
• It allows gametes to have twice the original number of chromosomes of the organism.
• It allows gametes to have half the original number of chromosomes that are genetically diverse
• All of the above

How many daughter cells are produced in mitosis?

• 4 new cells
• 2 new  identical cells
• One new cell
• none of these
