Detailed explanation-1: -The rate of translocation in the phloem was observed to decrease steadily after a plant was placed in an environment without oxygen for several minutes. Why did this happen? The cells in the plants stop respiring. The xylem no longer takes in water for the plant.

Detailed explanation-2: -Because translocation connects distant components of the plant body, xylem and phloem have long been considered to fulfill a role in communicating between organs, through the movement of plant hormones and other signaling molecules. Such signals are envisaged to move with assimilates by mass flow.

Detailed explanation-3: -The movement of sugar made as a result of photosynthesis to the rest of the plant for respiration and other processes is known as translocation. We already know that translocation occurs in phloem vessels. Generally, it happens between the sources and the sinks.

Detailed explanation-4: -Material like sucrose is transferred into phloem tissue using energy from ATP. This increases the osmotic pressure of the tissue causing water to move into it. This pressure moves the material in the phloem to tissues which have less pressure. This allows the phloem to move material according to the plant’s needs.

Detailed explanation-5: -Translocation occurs within a series of cells known as the phloem transport system, which is the most important digestive tissue of plants. Nutrients move to phloem as solutes in a solution called phloem liquid.
