NEET BIOLOGY

Detailed explanation-1: -Translocation is the movement of elements within a plant from leaves to other tissue. Plants’ phloem, a type of vascular tissue, is where translocation takes place. Sugars that are produced by photosynthesis or that are stored in plant tissues like roots, bulbs, and tubers are examples of sugar sources.

Detailed explanation-2: -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.

Detailed explanation-3: -In the accompanying animations, we described the pressure flow model of phloem translocation, which is currently the most widely accepted model for how translocation occurs. In the first step of this model, sugar (mainly sucrose) is actively transported from source cells into the sieve tubes of the phloem.

Detailed explanation-4: -Ans. Organic solutes such as sucrose are transported from the source to the sink through the phloem tissues of the vascular network. The active transport of phloem is distinguished from passive transport because both phloem loading at the source and unloading at the sink are accomplished through active transport.
