Question

briefly explain the transport of water and Minerals in plants

Answer 1

Plants have two systems for the transportation of substances - using two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots. Plants have adaptations to reduce excessive water loss. Phloem transports synthesized food from the leaves to the rest of the plant body.

Water from the roots is pulled up by this tension. At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids.

Answer 2

the transport system or a vascular wonder of a higher plant consists of xylem and phloem tissues . xylem carry water and Minerals upward from the route to the leaves while phloem carry food manufactured by the leaf to different part of the plant for utilisation and storage .

the food prepared in the leaves is transport to other part of the plant in the form of sucrose (a kind of sugar ) the movement of food from the leaves to the other parts of the plant where it is utilised or stored is called translocation of food.
