• Leaves

4
Roots

5
Parts of root

• Primary root
• Secondary root
• Root hairs

6
Types of roots

• Taproots
• Fibrous roots
• Fleshy roots (storage taproot)

7
Stems

• Vascular system
• Xylem vessels-water and nutrients
• Phloem vessels- energy from photosynthesis
• Cambium
• Nodes- leaf attachment

8
Types of stems
