Life cycles and reproduction

I can explain the role of reproduction as part of the life cycle of humans and other organisms.

Lesson details

Key learning points

  1. All living organisms have a life cycle.
  2. All life cycles include stages of growth and reproduction.
  3. In humans, the reproduction stage of the life cycle involves producing a baby that grows into a new human.
  4. In some plants, the reproduction stage of the life cycle involves producing a seed that grows into a new plant.

Common misconception

Sexual reproduction occurs in animals but not in plants.

The lesson contains a section on plant sexual reproduction.

Keywords

  • Life cycle - A life cycle is the stages a living organism goes through in its life.

  • Growth - The growth of an organism is an increase in size due to making more cells.

  • Reproduction - Reproduction is a common process where living organisms make offspring.

  • Zygote - A zygote is the fertilised egg of a human, and the first stage in the life cycle.

  • Sexual reproduction - Sexual reproduction is the process of making offspring where half the DNA is passed from each parent.

Pupils could come up with their own examples of a lifecycle for a different organism to share with the class.
