Question

How is food transported in plants?

Answer 1

Phloem, with its set of companion cells, sieve tubes, fibres and parenchyma, transports food materials from the leaves to different parts of the plant. This activity is called translocation. The transportation of food in phloem is achieved by utilising the energy from ATP molecules which helps in creating osmotic pressure, thus creating a concentration gradient wherein food from the area of higher concentration to translocate to the area of lower concentration.
