What is translocation ? How it take place in plants ?

Explanation

Transport of soluble product of photosynthesis ot food from leaves to other parts of plants is called translocation. For translocation, food molecules enter the part of the phloem called the sieve tubes where they can be transported upwards or downwards to all parts of the plant including roots. Translocation is achieved by utilising energy from the ATP that provides osmotic pressure required for upward and downward movement of food.
