'Source' is the part of a plant where substances are produced (e.g. leaves for sucrose, amino acids) or enter the plant.

'Source' is the part of a plant where substances are produced (e.g. leaves for sucrose, amino acids) or enter the plant.Explanation:

When a plant is actively photosynthesising and growing, the leaves are generally the major sources of translocated materials. They are constantly producing sucrose, which is carried in the phloem to all other parts of the plant.

Answer 2

Answer:
