Question

how did scientists that the food is transported through the xylem ?

Answer 1

Answer:

hey mate here is the answer

Explanation:

The xylem transports water and minerals from the roots up the plant stem and into the leaves.

In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.

Vessels

Lose their end walls so the xylem forms a continuous, hollow tube.

Become strengthened by a chemical called lignin. The cells are no longer alive.

Lignin gives strength and support to the plant. We call lignified cells wood.

Transport in the xylem is a physical process. It does not require energy.
