Worksheet: Reproduction

In this worksheet, we will practice describing asexual and sexual reproduction, and outlining advantages and disadvantages of each.

Q1:

Which of the following statements is not true about asexual reproduction?

  • AAsexual reproduction does not involve combining genetic material from different organisms.
  • BAsexual reproduction involves meiosis.
  • CAsexual reproduction involves mitosis.
  • DAsexual reproduction results in clones of a parent being formed.
  • EAsexual reproduction only involves one parent.

Q2:

A new disease targeting potato crops is developing. Which of the following best explains why it is advantageous for a population of potatoes to have been produced by sexual reproduction?

  • AThere is less genetic variation within the population, which means some plants may have alleles that help them defend against this new disease.
  • BThere is more genetic variation within the population, which means all the potato plants will survive infection with this disease.
  • CThere is more genetic variation within the population, which means some plants may have alleles that help them defend against this new disease.
  • DThe process of sexual reproduction takes longer, so the potato plants have longer time to develop resistance to this disease.

Q3:

What type of cell division forms gametes?

  • AMeiosis
  • BMitosis

Q4:

For the following examples, select the correct type of reproduction (asexual or sexual) that is being described.

An area of forest has been devastated by forest fires. The remaining trees rapidly produce small saplings from their roots.

  • AAsexual reproduction
  • BSexual reproduction

A bee carries pollen grains from one plant to the ovules of another.

  • AAsexual reproduction
  • BSexual reproduction

A female shark that has been isolated from male sharks produces eggs containing small embryos.

  • AAsexual reproduction
  • BSexual reproduction

Q5:

What is a zygote?

  • AA fertilized egg cell
  • BA fertilized sperm cell
  • CA developed embryo
  • DAn adult sperm cell
  • EAn undeveloped egg cell

Q6:

Give the scientific term for the specialized, haploid cells that fuse together to create a zygote when organisms reproduce sexually.

  • AGametes
  • BBody cells
  • CWhite blood cells
  • DAlleles
  • ERed blood cells
