Direction: The following question consists of two statements - Assert...
A is true but R is false. The transport or movement of soluble products (sugar) of photosynthesis from leaves to other parts of the plant is termed as translocation. It occurs in the part of vascular tissue known as phloem. The translocation in phloem is mainly achieved by utilising energy by expenditure of ATP. Assertion is true, but Reason is false.

Direction: The following question consists of two statements - Assert...
Assertion: Translocation of sugar occurs through the phloem.
Reason: It is achieved by diffusion of sugars through phloem.
Explanation:
The phloem is a type of plant tissue that is responsible for the transport of sugars, nutrients, and other organic molecules from the leaves to other parts of the plant, such as the roots, stems, and fruits. This process is known as translocation.
Translocation of sugar in plants occurs through the phloem tissue, which consists of specialized cells called sieve tubes. These sieve tubes are connected end-to-end to form a continuous tube-like structure. The movement of sugars from one part of the plant to another is facilitated by the process of diffusion.
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. In the case of translocation in plants, sugars are actively loaded into the sieve tubes at the source, which is usually the leaves. This creates a higher concentration of sugars in the sieve tubes.
As a result of this concentration gradient, the sugars diffuse from the source to the sink, which is the part of the plant that requires the sugars, such as the roots or developing fruits. This diffusion process allows for the translocation of sugars through the phloem.
In summary, the assertion that translocation of sugar occurs through the phloem is true. However, the reason provided, which states that it is achieved by diffusion of sugars through phloem, is false. While diffusion plays a role in the movement of sugars, it is not the sole mechanism responsible for translocation. Other processes, such as active loading and unloading of sugars, as well as pressure flow, also contribute to the movement of sugars in the phloem. Therefore, the correct answer is option C: A is true, but R is false.
Reason: It is achieved by diffusion of sugars through phloem.
