Question

Which of the following is related with transfer of food material?

• A. Xylem
• B. Collenchyma
• C. Phloem
• D. Parenchyma

Answer 1

The correct option is C Phloem

Xylem tissue is comprised of dead cells involved in the process of transport of water and minerals. Transport of water is under the influence of transpiration pull and is a physical process.

Phloem tissue is comprised of living cells involved in the process of translocation of sugars. Translocation of sugars requires living cells and is a physiological process. The sugars are transported under the influence of pressure difference between source and sink, which leads to mass flow.
