Detailed explanation-1: -Final answer: The carbohydrates synthesised in the leaves are transported through sieve tubes most commonly in the form of sucrose.

Detailed explanation-2: -Final answer: The form of sugar transported through phloem is sucrose.

Detailed explanation-3: -Carbohydrates are translocated from leaves to roots and storage organs along the phloem in the form of sucrose. They are translocated through living sieve elements of phloem.

Detailed explanation-4: -The phloem is the means by which the products of photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots, and to developing leaves, nectaries, fruits and seeds (Baker and Milburn, 1989).
