Transpiration is the loss of water through leaves by evaporation

• True

• False

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

Transpiration helps the plant

• make more sugars at night

• move sugars from the leaf to be stored in the stem & roots

• make more chloroplasts

• move water from the roots to the stem and leaves

Translocation is...

• the movement of water through the plant from the leaves to the roots

• the movement of water from the roots to the stem and leaves

• the movement of glucose through the plant from the leaves to other parts of the plant

• the movement of glucose from the roots to the stem and leaves
