Every living thing on Earth goes through a life cycle. As any organism grows, it changes. In some organisms, the stages look very different; a flowering plant changes from a tiny seed into a plant, for example. Tadpoles look very different from an adult frog.

In mammals (such as humans), the young look like a smaller version of their parents.

Life Cycles Facts

  • Every animal and plant has a life cycle; that is a number of different stages they go through during their lifetime.
  • The mayfly has the shortest life cycle of any animal. In some species the mayfly only lives for a few minutes in their adult form.
  • Metamorphosis is the process by which some animals change from one form to another. These forms can look very different indeed. For example, butterflies start life as an egg, then hatch out into a caterpillar, before they form a chrysalis and finally emerge as a butterfly.
  • The male part of a flower is the stamen, and the female part is the pistil.
  • Pollinators, such as bees and other insects, carry pollen from one flower to another, so that the plants can reproduce.
