.How transportation of water and minerals happen in a tall tree? Write in brief
Answers
Answer:
Transportation of water and minerals happen in a tall tree by the process of xylem through root hairs
Answer:
Root pressure can transport water and dissolved mineral nutrients from roots through the xylem to the tops to small heights. In taller plants, transpiration pull cause movement of water into roots from soil as well as its upward movement in plant body through xylem
Explanation:
There are main two physical forces or pressures which helps in the transport of water in tall plants. They are :
ROOT PRESSURE -
The pressure which is present in the Xylem of the roots is known as root pressure.
It is responsible to push water upwards to small heights.
It cannot efficiently push water upwards in tall plants.
In tall plants, this pressure has a role to gently push in the net process of transportation of water.
In tall trees, it checks the continuation of water chains in the Xylem.
TRANSPIRATION FORCE :
It is believed that water is mainly pulled through this force.
A name is given to the process of water transport when it occurs through transpirational force. This is called model of cohesion-tension-transpiration pull.
