Detailed explanation-1: -translocation. The correct answer is Option B. Explanation of the correct answer: The transport of food from leaves to different parts of a plant is called translocation. It takes place with the help of a complex permanent conducting tissue called phloem.

Detailed explanation-2: -Translocation occurs in the phloem tissue, which consists of tube-like structures called phloem vessels. These phloem vessels run from the leaves into every other part of the plant and are responsible for transporting dissolved organic solutes, such as sucrose and amino acids, from the sources to the sinks.

Detailed explanation-3: -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-4: -Translocation is the movement of sugar produced in photosynthesis to all other parts of the plant for respiration and the other processes described above. This occurs in phloem cells.

Detailed explanation-5: -Listen to pronunciation. (TRANZ-loh-KAY-shun) A genetic change in which a piece of one chromosome breaks off and attaches to another chromosome. Sometimes pieces from two different chromosomes will trade places with each other.
