Plant Processes and Functions

The video tutorial explains the transportation of water, nutrients, and food in plants. It covers the roles of roots, xylem, phloem, and the processes of photosynthesis and transpiration. Roots absorb water and nutrients, xylem transports them, phloem distributes sugars, and transpiration helps in cooling. The tutorial also highlights the importance of these processes for plant survival.
