Xylem transports water and solutes from the roots to the leaves.

Ploem
Phloem transports food from the leaves to the rest of the plant.
2 of 8
Transpiration
Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots.
3 of 8
Translocation
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis.
4 of 8
How does light effect the transpiration rate?
In bright light transpiration increases. The stomata (openings in the leaf) open wider to allow more carbon dioxide into the leaf for photosynthesis.
5 of 8
How does temperature effect the transpiration rate?
Transpiration is faster in higher temperatures. Evaporation and diffusion are faster at higher temperatures.
6 of 8
How does wind effect the transpiration rate?
Transpiration is faster in windy conditions. Water vapour is removed quickly by air movement, speeding up diffusion of more water vapour out of the leaf.
7 of 8
How does humidity effect the transpiration rate?
Transpiration is slower in humid conditions. Diffusion of water vapour out of the leaf slows down if the leaf is already surrounded by moist air.
