TRANSPORT SYSTEM IN PLANTS

Definition: the evaporation of water from a plant.

90% of the absorbed water by the roots lost by

evaporation

Factors affecting transpiration:Light – L↑, T↑

Temperature – T↑, T↑

Humidity – H↑, T↓

Wind speed – W↑, T↑

Water availability – WA↓, T↓

Altitude - A↑, T↑ (as pressure decrease)

Main function of stomata is to allow gases to diffuse in and out of the leaf.Photosynthesis – CO2 diffuses into leaf and O2 diffuses out of the leaf.When stomata open, water vapour is released to the surroundings.
