The process by which plants make food is named as photosynthesis. Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air. Plants can perform photosynthesis only through leaves and not by other parts of the plant. Leaves have a special green pigment called chlorophyll which helps in the absorption of energy from the sun. The chloroplast present in the cells play a vital role in this process. The various steps involved in the process of photosynthesis are given below:
- Absorption of light energy through the sun by chlorophyll present in leaves.
- Conversion of light energy chemical energy. In this process, the water molecule splits into its respective components hydrogen and oxygen.
- Carbon dioxide is reduced into carbohydrates like glucose by light energy utilizing the hydrogen and oxygen produced in the above step.
The reaction involved in photosynthesis is:
6CO2+6H20→C6H12O6+6O2

Two angles are called complementary angles, if their sum is one right angle i.e. 90°.
Each angle is called the complement of the other.
Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.

Compounds
1. Compounds are pure substances.
2. They are made up of two or more elements combined chemically.
3. The constituents of a compound are present in a fixed ratio.
4. Compounds have fixed properties. For example, a particular compound will have fixed temperatures at which it melts and boils.
5. A compound can have properties different from its constituents, as a new substance is formed when the constituents are chemically combined.
Mixtures
1. Mixtures are impure substances.
2. They are made up of two or more substances mixed physically.
3. The constituents of a mixture are present in varying ratios.
4. Mixtures do not have fixed properties. Their properties depend on the nature of their components and the ratios in which they are combined.
5. In mixtures, no new substance is formed. The properties of a mixture are the same as the properties of its constituents.
