Worksheet: Mitosis

In this worksheet, we will practice recalling the stages of the cell cycle, describing the different stages of mitosis and explaining the importance of mitosis for living organisms.

Q1:

What is produced at the end of mitosis?

  • AFour genetically identical daughter cells
  • BFour gametes for reproduction
  • CTwo genetically identical daughter cells
  • DTwo genetically different daughter cells
  • EFour genetically different daughter cells

Q2:

Which of the following is not a correct description of a stage in the cell cycle?

  • ADuring stage 3, the cytoplasm and cell membrane divide to form four new cells.
  • BDuring stage 2, the cell undergoes mitosis from prophase to telophase.
  • CDuring stage 3, the cytoplasm and cell membrane divide to form two new cells.
  • DDuring stage 1, new subcellular structures are synthesized.
  • EDuring stage 1, DNA replicates to form two copies of each chromosome.

Q3:

Around 300 million body cells die and need replacing every minute. How many body cells need to be replaced per second?

  • A3.5 million
  • B18 million
  • C5 million
  • D3 million
  • E6 million

Q4:

Which of the following is not a purpose of mitosis?

  • AReplacing dead cells
  • BProduction of gametes
  • CAsexual reproduction
  • DGrowth
  • ERepairing damaged cells

Q5:

Which of the following is not correct about asexual reproduction?

  • AIn asexual reproduction, offspring are produced by mitosis.
  • BAsexual reproduction produces clones of the parent.
  • CAsexual reproduction can be used by organisms when mates are not available to reproduce sexually with.
  • DAsexual reproduction increases the genetic variation in a population.
  • EAsexual reproduction reduces the genetic diversity of a population.

Q6:

What subcellular structures pull the chromosomes apart in mitosis?

  • AEndoplasmic reticulum
  • BRibosomes
  • CChromatids
  • DSpindle fibers
  • ECytokinesis

Q7:

What stage of the cell cycle takes the longest to complete?

  • AStage 3 (cell division)
  • BStage 1 (DNA replication)
  • CStage 2 (mitosis)
  • DAll the stages take the same amount of time.
