Recall the equation for photosynthesis

• Oxygen + carbon dioxide -> glucose + water

• oxygen + glucose -> carbon dioxide + water

• oxygen + water -> carbon dioxide + glucose

• carbon dioxide + water -> oxygen + glucose

Recall the equation for aerobic respiration

• Oxygen + carbon dioxide -> glucose + water

• oxygen + glucose -> carbon dioxide + water

• oxygen + water -> carbon dioxide + glucose

• carbon dioxide + water -> oxygen + glucose

Select the limiting factors

• Water

• Carbon dioxide

• Temperature

• pH

• Light intensity

(a)  

Name the cells which surround the stomata

(a)  

Name two factors which increase the rate of water loss

• increase acidity

• increase oxygen

• increase temperature

Most of the chloroplast cells are found in the

• upper epidermis
• pallisade mesophyll layer
• lower epidermis
• stomata
