Students are required to know the following;
Students should be able to explain how the structure of root hair cells, xylem and phloem are adapted to their functions.
Root hair cells are adapted for the efficient uptake of water by osmosis, and mineral ions by active transport. Xylem tissue transports water and mineral ions from the roots to the stems and leaves. It is composed of hollow tubes strengthened by lignin adapted for the transport of water in the transpiration stream. The role of stomata and guard cells are to control gas exchange and water loss.
AT 6, 7 Investigate the distribution of stomata and guard cells.
