What do you know about photosynthesis?

What do plants 'eat'?

Water - the root hairs on the roots absorb water from the soil

Minerals - The water contains minerals

Needed for growth.

Carbon dioxide - Via stomata in the leaf, the plant extracts the gas, carbon dioxide, from the air.

Photosynthesis

The plant produces 

- glucose

- oxygen

The plant needs

- carbon dioxide

- water

- sunlight

Photosynthesis

Occurs in the chloroplasts

Only when there is sunlight!

- Sunlight gives energy

Oxygen passes out of the leaf through the stomata.

How does a plant produce glucose?

1. Engergy rich substance

2. Convert it into other nutrients:

• starch (zetmeel)
• fats
• proteins (eiwitten)
• vitamins

Storage of food

• Tuber (knol) - swollen roots or thick underground stems (potato)

• Bulb (bol) - thick leaves that lie very closely together (onion)

• Seeds
