• B. (B) The part where food is synthesized is called source and while part where it is utilized is called sink.
• C. (C) Food has to travel from source to sink. This movement of food from one part to the other part is called translocation of food.

(D) All of the above

Answer 2

Explanation:
The transport of food in plants is called translocation. It takes place with the help of a conducting tissue called phloem. Phloem transports glucose, amino acids and other substances from leaves to root, shoot, fruits and seeds. The transport of food in plants depends upon the following factors:All plant parts require supply of food for nutrition and development.Chloroplasts are confined to green cells of leaves where food is synthesized. The non green parts like root and stem receive food from lives.The part where food is synthesized is called source and while part where it is utilized is called sink.Food has to travel from source to sink. This movement of food from one part to the other part is called translocation of food.Hence the correct option is (D).
