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.


What is produced at the end of mitosis?

  • ATwo genetically different daughter cells
  • BFour gametes for reproduction
  • CFour genetically identical daughter cells
  • DFour genetically different daughter cells
  • ETwo genetically identical daughter cells


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

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


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

  • A18 million
  • B6 million
  • C5 million
  • D3.5 million
  • E3 million


Which of the following is not a purpose of mitosis?

  • AReplacing dead cells
  • BAsexual reproduction
  • CRepairing damaged cells
  • DProduction of gametes
  • EGrowth


Which of the following is not correct about asexual reproduction?

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


What subcellular structures pull the chromosomes apart in mitosis?

  • AChromatids
  • BEndoplasmic reticulum
  • CSpindle fibers
  • DRibosomes
  • ECytokinesis


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

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