Transpiration - bridging between osmosis and transpiration

A resource aimed at advanced biology students, this worksheet links topics on osmosis and transpiration. The worksheet begins with a recap of basic knowledge related to osmosis, predicting water movement between cells through use of their water potential values. The worksheet then moves on to consider water potential gradients that exist through an entire plant followed by the structure (as seen in longitudinal and transverse section) of roots.

Key words: osmosis, water potential, apoplast, symplast, cell wall, casparian strip, active transport, minerals, epidermis, endodermis, root hair cells, cortex, xylem, transpiration
