Photosynthesis is the process that plants use to make their own food (glucose) using energy from light.

Photosynthesis happens in the chloroplasts of plant cells.

The glucose produced by photosynthesis is used for growth and various other life processes in the plant.

1. Sunlight - Provides light energy.

2. Carbon dioxide - Diffuses into the leaves from the air.

3. Water - Absorbed by the roots and transported to leaves.

4. Chlorophyll - Green pigment found in chloroplasts that absorbs light energy.

carbon dioxide + water (+ light energy) ➔ glucose + oxygen

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, which is necessary for photosynthesis.

1. Leaves have a large surface area to absorb light.

2. Leaves are thin to provide a short diffusion distance for gases.

3. Palisade cells have lots of chloroplasts.

4. Stomata allow carbon dioxide to enter the leaf and oxygen to exit.

5. Veins deliver water to leaf cells.

Roots are adapted to maximise absorption.

Root hair cells provide a large surface area for absorption of water and mineral ions, which are needed for photosynthesis and to keep the plant healthy.

Animals get their energy from the food they eat, while plants make their own food (glucose) through the process of photosynthesis.
