Plant Organs

The function of the roots is:

• Anchor the plant and absorb sucrose and minerals from the soil

• Absorb water only from the soil

• Absorb minerals and water from the soil and anchor the plant

• Absorb nutrients and water from the soil

The leaf has a shiny, waxy cuticle around it to

• increase the rate of photosynthesis
• attract more light
• control water loss
• stop carbon dioxide and oxygen gases escaping

The important gases, carbon dioxide and oxygen, enter and leave the leaf through the

• upper epidermis
• phloem
• stomata
• guard cells
