How do substances for photosynthesis enter and leave the plant?

Answer 1

The gas for photosynthesis...carbon dioxide diffuses into the plant through its stomata ('holes' in the leaf's underside).

Water is transported through the plant in the xylem tube (waterproof tube that makes up part of the plants veins and covers the whole plants structure) as it is drawn up from the roots where it is absorbed. It is drawn up by the water evaporationg through the stomata.

The light obviously enters the leaf and enters the chloroplasts where it combines with the chlorophyll to provide the energy for the photosynthesis reaction.

The products from photosynthesis...glucose and oxygen are removed from the plant leaves. Glucose through the phloem tube (another of the veins) and oxygen through diffusion through the stomata or it is used up in respiration.

Answer 2

The substances for photosynthesis enter and leave the plant via the stoma. Carbon dioxide and water vapor enter a leave via the stoma and diffuses into the mesophyll cell. Oxygen leaves the stoma during photosynthesis.

Answer 3

The ingredients enter and exit from the stomata of the plant. the stomata is a pore on a plant.

Answer 4

Carbon dioxide molecules are absorbed from the air into the leaves.

Answer 5

There are two raw materials. H2O is entering via roots.
