Plants make their food through a process called Photosynthesis.

Photosynthesis is a chemical process that occurs in every green plant. Plants produce glucose during photosynthesis.

Photosynthesis takes place mostly in the plant's leaves. Sunlight, chlorophyll, water and carbon dioxide are needed for Photosynthesis.

Plants take energy from the sun. Light energy is consumed by a green substance called chlorophyl, during Photosynthesis. Chloroplasts are mainly found in the leaves.

During the day, the rate of photosynthesis is sufficiently high.

The leaf tissues are adapted for efficient gas exchange and photosynthesis..

The broad green leaves of plants provide a large surface area for maximum absorption of light.

Plants absorb minerals from the soil through their roots.

Plants need to take up water and minerals from the soil and transport them to the leaves for photosynthesis. Xylem transports water and minerals from the roots to the shoots and leaves.

Water enters the root hair cells by osmosis. Root hair cells have large surface area for absorbing water and mineral ions.

Root cells have thin walls that reduces the distance for water transfer in osmosis.

Mineral ions can be absorbed through the hairs of the root cells.

The factor that limits photosynthesis

The amount of photosynthesis may be affected by low temperature, shortage of carbon dioxide and shortage of light.

The rate of photosynthesis also affects by the amount of chlorophyll .

Increasing the light intensity increases the rate of photosynthesis.

As the concentration of carbon dioxide increases, the rate of phosynthesis increases.

An increase in temperatures in greenhouses increase the rate of photosynthesis.
