Explain pressure flow hypothesis of translocation of sugars in plants.
According to the strain float hypothesis, meals is ready withinside the plant leaves withinside the shape of glucose. Before moving into the supply cells gift withinside the phloem, the organized meals is transformed into sucrose. Water movements from the xylem vessels into the adjoining phloem, thereby growing the hydrostatic strain withinside the phloem. Consequently, the sucrose movements thru the sieve cells of the phloem. The sucrose already gift withinside the sink location is transformed into starch or cellulose, thereby lowering the hydrostatic stress withinside the sink cells. Hence, the strain distinction created among the supply and the sink cells lets in sugars to be translocated from the previous to the latter. This starch or cellulose is eventually eliminated from the sink cells via lively transport.
