Photosynthesis

Photosynthesis is essential to understanding why all life on earth depends upon the existence of plants.

The Process of Photosynthesis

Photo means light and synthesis means putting together.

During photosynthesis minerals and water are combined with carbon dioxide from the air.

How Does Photosynthesis Help us?

During photosynthesis oxygen is released into the air.

When we breath air, we take in oxygen and release carbon dioxide.

Plants take in carbon dioxide and release oxygen.

How do Plants Produce Their own Food?

Most plants can produce all their own food because they contain chlorophyll.

Chlorophyll is a substance that makes the leaves of most plants green.

Green plants use chlorophyll to capture sunlight.

The they use the energy from sunlight to make food.

Cycle of Nature Green plants use the sun’s

energy to change water, minerals and carbon dioxide into food and oxygen.

Oxygen is breathed by animals.

Food helps the plants grow. Plants become food for the

animals. When plants and animals die

they decay and return to the soil.

There would be no food for plant eating animals, so they would die.

There would be no food for the meat eating animals.

There would be no oxygen to breath.

The cycle of nature would be broken-

lifeless planet.

If there were no plants...

Food Energy

People get energy from plants in the form of food.

Food energy is stored in almost every part of a plant.

Food energy is the fuel that makes your body work.

Plants and People

Plants are part of our lives in many ways.

When we are hungry we eat plants for food.

Every time we take a breath we use oxygen that was released by green plants.

It is a cycle of give and take, borrow and return.
