Question

How does transpiration help in the transport of water and minerals in plants
Grade seven question?

Answer 1

Answer:

The evaporation of water from the leaf surface, known as transpiration also produces a pulling force that causes the water to move upwards. The transpiration of water and dissolved mineral salts, from the root to the stem, leaves, flowers and other parts of the plants takes place through the xylem.

Answer 2

Answer:

The vascular tissue for the transport of food to the various parts of the plant is phloem. A lot of water is lost by plants in the form of vapour through stomata during transpiration. Transpiration generates a force which pulls up water absorbed by the roots from the soil, to reach the stem and leaves.
