Life Processes Class 10 Science Chapter 6 - Transportation in Plants

Topics covered in this 10th CBSE Science video are as follows :-
1) Introduction - What is mean by Transportation in Plants?
2) Transport of water and minerals - Xylem
3) Transport of food & other substances - Phloem

Plant need carbon dioxide, water and other raw materials to prepare their food and for body growth.
These raw materials need to be transferred from one part to other. for that plants have specially organised conducting tubes called as xylem and phloem.
Xylem moves water and minerals from roots to body parts and phloem transport product of photosynthesis from leaves to other parts of the plant.
The concentration of water outside the roots is higher than inside. Hence water is diffused into the root cells. This process is called osmosis.
Compared to this, the ionic concentration inside the roots is higher than outside, hence to absorb ions from lower concentration to higher concentration, root cells require energy.
Water and minerals collected in roots undergo steady upward pressure called root pressure with which water moves to upper body parts, but this pressure is insufficient to move water to higher body parts.
The loss of water in the form of vapours through the upper body parts is called transpiration. With transpiration water and minerals are transported to higher body parts.
It creates continuous upward suction allowing water to be transported to upper body parts
It helps in temperature regulation i.e. excess heat is eliminated via water vapours.
Xylem allows to connect and transport water and minerals from roots to all body parts since it interconnects vessels and tracheids of roots, stems and leaves.

Plant prepares their food with the help of photosynthesis. This food need to be transported to storage organs, roots, fruits, seeds and other body parts.
The transport of soluble products of photosynthesis is called translocation.
Translocation occurs in sieve tubes with the help of companion cells in a vascular tissue called as phloem.
Phloem also transports amino acids and other substances.
