Question

How does translocation of food and other substances take place in plants?

Accepted Answer

Translocation takes place in phloem tissue (sieve tubes with companion cells). Sucrose is loaded into phloem using ATP energy. This increases osmotic pressure, causing water to enter the phloem from xylem. The resultant high pressure moves the sap to tissues with lower osmotic pressure.
