Photosynthesis
Photo means light and synthesis means put together.
Photosynthesis
is how plants use light and water to make sugar. Sugar is
created in the green parts of a plant and every animal on
Earth depends on it. Without plants we would have no food to
eat or oxygen to breathe. Here is a picture to show how it
happens. |

Plants
absorb a common gas called carbon dioxide, pull water up
through their roots and use light to make sugar. Plants use
the sugar to grow. Plants give off oxygen as a by-product.
The green parts of the plant makes
the sugar and oxygen. |
Carbon dioxide + water + sunlight = sugar + oxygen

Experiment
Consider the vines in a rain forest. Why do these cling to trees and grow upwards? Why might we choose the sunniest place in the garden to grow vegetables and fruit? |
