Question

write a short note on source to sink relation

Answer 1

Dear student,
Please find below the solution to the asked query

The source and sink relationship in plants is reversible because food synthesised in leaves (source) is first transported to growing parts and storage organs (sink) and then back form sink (storage organs) to the growing parts at the time of need. This helps the plant to perform necessary life activities and survive during unfavourable conditions when the rate of photosynthesis is low or negligible.

The source and sink relationship in plants is reversible because food synthesised in leaves (source) is first transported to growing parts and storage organs (sink) and then back form sink (storage organs) to the growing parts at the time of need. This helps the plant to perform necessary life activities and survive during unfavourable conditions when the rate of photosynthesis is low or negligible.I plants source to sink mechanism takes place.In this mechanism,the food stored in the form of starch act as source and the plant part which needs it became sinIt is bidirectional (interchangeable).
