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

What is the name of the tall and long, packed cells (part G) directly under the upper epidermis?

• Palisade cells

• Guard cell

• Spongy layer

• Lower epidermis
