What is a lifecycle?

Why do you think it is important to know about lifecycles of animals? Do you think if we do not learn about other species that they will survive or be more likely to become extinct?

All Lifecycles: Begin with fertilization of egg or seed Then Metamorphosis End with adult

All Animals and plants are Categorized or Classified Can you categorize or classify these things?

Life Cycle of a Plant

A plant’s life cycle starts with a seed. Inside the seed is a tiny new plant. The outside of the seed has a special covering called a seed coat.

When the seed gets the right amount of water, warmth, and air, it can begin to grow.

As the sprout continues to develop, it will grow roots, a stem, leaves, and flowers which will form more seeds and fruit.

Life Cycle of a Frog

Metamorphosis Metamorphosis is the changes that a frog goes through during its life cycle. There are four main stages in the life cycle of the frog.

Egg The first stage in the life cycle of the frog is the egg. A frog lays many eggs at one time. The eggs are covered with a jellylike coating.

Tadpole The second stage of the frog life cycle is the tadpole. Hatched tadpoles have gills for breathing in the water. They have a tail, but no legs.

Metamorphosing frog In the third stage the tadpole begins to look more like an adult frog.

Adult Frog Once the lungs form and begin to work, the gills and tail disappear. The adult frog is now ready to live on land.

Life Cycle of a Butterfly

The First Stage of a Butterfly's Life. The egg is the first stage of a butterfly’s life.

The eggs are laid in a safe location on or near the plants that the caterpillar will eat.

The Second Stage of a Butterfly’s Life The second stage is the larva or caterpillar.

The Third Stage of a Butterfly’s Life The chrysalis or pupa is the hard covering formed around the larva. Inside this covering, the pupa changes

The Last Stage of a Butterfly’s Life. The final stage is the pupa breaking open; an adult butterfly emerges.

Metamorphosis The development from an egg, to larva, to pupa, and adult butterfly is metamorphosis.
