(1) As per pressure flow hypothesis, preparation of food takes place inside the plant in the form of glucose.
(2) The prepared food converted into sucrose before transporting it to the source cell
(3) Hydrostatic pressure increases due to movement of water into adjacent phloem.
(4) Movement of sucrose takes place through the phloem sieve cells.
(5) The sucrose which is already present in the sink region is converted into starch or cellulose, which reduces the hydrostatic pressure in the sink cells. Hence, due to the difference in pressure between the source and sink translocation of sugar takes place from one place to other and removal of sucrose takes place by active transport.Answered by Abhisek | 1 year ago
Differentiate between Guttation and Transpiration.
Differentiate between Apoplast and Symplast pathways of movement of water in plants
Differentiate between Imbibition and Diffusion
Differentiate between Osmotic Pressure and Osmotic Potential
Differentiate between Transpiration and Evaporation
