Question

How does phloem sap move in a plant?

Answer 1

Phloem sap movement in plants:

1. In a plant's green sections, food is produced. The photosynthetic cells are necessary for the nutrition of the non-green components. The vascular tissue phloem transports the food in the form of sucrose. Learn more about phloem transfer now. Transportation takes place in the sinking source direction. Translocation of organic solvents refers to the movement of organic solutes through phloem sieve tubes within a plant.
2. Long columns with holes in the end walls are formed by sieve tubes in the phloem. These perforations allow cytoplasmic strands to pass through, establishing a continuous channel.
3. Mass flow versus pressure flow is the method for sugar translocation in higher plants that is most widely accepted. It happens during the subsequent steps.
4. The leaves prepare glucose, which is then transformed into sugar.
5. Active transport is used to carry the sucrose-containing sugar from the companion cells into the phloem sieve tube cells, which are still alive. The phloem becomes hypertonic as a result of this.
6. Endosmosis is the process by which water in xylem vessels close to the phloem transfers.
7. Phloem SAP travels from a location with higher osmotic pressure to an area with low pressure as osmotic pressure rises.
8. At the sink, osmotic pressure is kept to a minimum.
9. Once more, active transport is needed at the sink to get the sugar from the phloem SAP into the cell, where it is used to produce energy during respiration.
