Roots

• What is a root?
• How is it an organ?

Functions of roots

• Taking up water & minerals
• Anchoring the plant
• Storing food reserves

Stems

Function of stems: 

- Support the flowers, leaves & fruit. 

- Keep the plant upright. 

- Store extra food. 

- Transport water, minerals & food through the plant. 

2 types of stems: 

- WOODY STEMS (trees & bushes)

Vascular system

All the vessels of a plant taken together

Function:  transport

1. water and minerals from the roots
   to other parts of the plant
2. glucose from the leaves
   to the other parts of the plant

Leaves

• Make food = photosynthesis
• Photosynthesis > in all green parts of a plant
• Photo = Light
• Synthesis = to make
