What will you learn in this lesson?

Reproduction keeps the kinds of living things going, and it happens in two ways: asexual, from one parent, and sexual, from two parents. In this lesson you compare them and learn examples such as budding, regeneration, vegetative propagation, and fertilization.

  • Compares sexual reproduction with asexual reproduction
  • Describes types of asexual reproduction: fission, budding, regeneration, and vegetative propagation
  • Defines fertilization as the joining of a sperm cell and an egg cell
  • Explains why offspring are exactly like their parent in asexual reproduction

💡 Tip: Remember: one parent = asexual, and the offspring are identical copies. Two parents = sexual, and the offspring carry traits from both, so they differ a little.

Worked examples from the Reproduction lesson questions

Reproduction that needs only one parent is called:
  • Asexual reproduction
  • Sexual reproduction
  • Fertilization
  • Pollination
✓ Asexual reproduction
In asexual reproduction, one parent produces offspring without needing sex cells from two parents.
What is the female sex cell?
  • The egg cell
  • The sperm cell
  • A pollen grain
  • A spore
✓ The egg cell
The egg cell is the female sex cell, and the sperm cell is the male sex cell.

What is the joining of a sperm cell and an egg cell called?
  • Fertilization
  • Budding
  • Regeneration
  • Fission
✓ Fertilization
Fertilization is the joining of the male sex cell with the female sex cell to form a fertilized egg that grows into a new living thing.
A small bump grows on a yeast cell, gets bigger, and then breaks off to form a new cell. What kind of reproduction is this?
  • Budding
  • Regeneration
  • Fission
  • Fertilization
✓ Budding
Budding is asexual reproduction in which a bud grows from the parent's body and then breaks off.
A starfish lost one of its arms, and a new arm grew back. What is this ability called?
  • Regeneration
  • Budding
  • Fission
  • Pollination
✓ Regeneration
Regeneration is the ability of some living things to replace lost parts of their bodies.

FAQ about the Reproduction lesson

What is the difference between sexual and asexual reproduction?

Asexual reproduction needs one parent and produces offspring identical to it, such as budding in yeast. Sexual reproduction needs two parents, in which a male sex cell joins a female sex cell, producing offspring that carry traits from both.

What is vegetative propagation?

Asexual reproduction in plants in which a new plant grows from a part of the parent plant, such as a stem, root, or leaf. Examples include planting palm offshoots and potato tubers.
