Photosynthesis is a process of plants to make their own Food and then toproduce Oxygen by using Light Energy, Carbon Dioxide, Water, & Nutrients from the soil.

Chloroplasts & Chlorophyll

Chloroplasts are the plastids that

chlorophyll, and chlorophyll is the

green pigment present in the plant

that help it for the process of

photosynthesis.

There are three main factors affecting photosynthesis and several corollary factors. The three main are:

1. Light  irradiance and wavelength2. Carbon Dioxide concentration3. Temperature

Photosynthesis is one of the most important chemical

reactions in the world. What are the reasons for this?

Photosynthesis makes food for plants and for animals.

We have already learned that plants feed themselves by using sunlight to convert carbon dioxide and water into food (sugar). Whenever the plant needs energy for itself it breaks down its stored food. Animals get their food by eating the plants so they depend on plants for their food.

Photosynthesis results in oxygen gas being made that is released by the plant into the atmosphere for living things to breathe.

Living things breathe in oxygen and breathe out carbon -dioxide all the time. Fortunately plants do the opposite. When plants are making food they breathe in carbon dioxide and breathe out oxygen. Therefore plants are extremely important to humans and animals as they give them oxygen to breathe and prevent us all from suffocating. Oxygen is needed by all living organisms to burn up food for energy.

Photosynthesis results in carbon dioxide gas being removed from the atmosphere.

Carbon dioxide is a greenhouse gas that is respon-sible for global warming.
