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?

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

Q2:

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.

Q3:

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

Q4:

Which of the following is not a purpose of mitosis?

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

Q5:

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.

Q6:

What subcellular structures pull the chromosomes apart in mitosis?

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

Q7:

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)
