How is food transported in plants?

Expert Answer:

Translocation of food takes place in sieve tubes of phloem, with the help of companion cells, in upward and downward direction. This translocation requires energy. Materials like sucrose is transferred into phloem tissue using energy. This increases the osmotic pressure of the tissue causing water to move into it.This pressure moves material in the phloem to tissues which have less pressure. Thus phloem can move materials according to the plant's needs.
