Transportation in Plants: Transportation of water and food take place by xylem(water) and phloem(food) through diffusion and osmosis.
Absorption by roots : Roots play an important role in absorption of water and minerals from the soil, which is conducted to all parts of the plant body through xylem.
Learn about the processes and their significance involved in absorption and conduction of water like 1) imbibition, 2) diffusion, 3) osmosis, 4) plasmolysis and 5) turgidity.
Transpiration: Loss of water, in the form of water vapour is called transpiration. --Learn different experiments showing transpiration in plants. --Transpiration can be measured by weighing methods and Ganong's photometer. The types of transpiration are : Stomatal (through leaves) , lenticular (through roots) and cuticular (through cuticle).
Photosynthesis: This module focuses on mechanism of photosynthesis. Processes of photosynthesis-; 1)Light reaction: It takes place only in presence of light and occurs in grana region of plastids. 2)Dark reaction - It is independent of light and occurs in stroma region of plastids. Also learn about the factors affecting photosynthesis.
