Transport notes

UNIT 2

Transport in plants 

Plants don’t have a circulatory system like animals, but they do have a sophisticated transport system for carrying water and dissolved solutes to different parts of the plant, often over large distance.














TRANSPIRATION MORE LIKE WATER CYCLE











 XYLEM

Xylem is woody tissue that carries water and minerals from the roots hroughout the plant and provides the plant with mechanical support.In transpiration process the loss of water from the leavesdrives themovement of water and minerals in the xylem.

 STOMATA

The rate of transpiration is directly proportional to the opening and number of stomata.

In the daytime, the stomata is open to release water in atmosphere, which is then broken down
 into oxygen and hydrogen. In return, the atmospheregives carbon-dioxide to the plant to complete
 its process of photosynthesis.
