Lesson 36: Leaves, roots and stem

Hi,

Plant physiology is not so exciting for most students. Hopefully this will add some zest for you.

I find this set of powerpoint slides very vivid. It covers the following parts of the syllabus in clear crisp slides:

• functions of roots, leaves and stem in a plant

• root hair cell and its various functions

• xylem structure and its functions

• phloem structure and its functions

• active transports and use of energy (ATP) to transfer molecules and ions

• osmosis and simple diffusion

• structure of vascular bundle, its location in the plant organs

• transpiration, transpiration pull, capillary action

• stoma and how it functions in gaseous exchanges

The parts about secondary growth, bark formation are not in our syllabus.
