SLIDE 3
- All animals and plants go
through an adult stage in their life cycle.
- Organisms of the same
type go through the same stages of change (mammals, birds, frogs, snakes, plants)

Human Life Cycle
SLIDE 5
3.Embryo - the early stage in which a plant or animal begins to grow 4.Infancy - the stage after a baby is born (0-2 years) 5.Childhood - the stage after infancy, gaining independence (2-12 years old) 6.Adolescence - the stage after childhood, usually includes rapid growth (ages 12-20) 7.Adult - the stage in which an organism if fully developed (in humans 20+ years)

- 8. Complete metamorphosis - has 4 distinct stages: egg,
larva, pupa, and adult. 9.larvae: the caterpillar or worm-like stage in the life cycle of some insects 10.pupa: an insect in the stage of its life cycle in which it changes from a larvae to an adult

The Life Cycle of Fish
- 11. Fry - tiny fish that resembles an
adult fish
- 12. Spawning - a method of
reproduction in which a very large number of eggs are laid so that some will survive predators
SLIDE 10
- 13. incomplete metamorphosis - has 3 distinct stages:
egg, nymph, and adult.
- 14. nymph - a young insect in the stage of its life cycle
in which is looks like a small adult

The Life Cycle of a Plant
1.Seed 2.Seedling 3.Adult plant
15.Germinate - to begin to grow from a seed *Life cycles can start over through germination
SLIDE 12
16.regeneration: the process of re-growing lost tissues.
✓ Spiders can regrow missing legs or parts of legs ✓ Sponge cells can divide and will regrow and combine exactly as before ✓ Starfish that lose arms can grow new ones
