|
|
|
uptake of water by root cells depends on osmosis.
|
|
|
upward movement of water depends on transpiration pull.
|
|
|
enzymes are not involved in the uptake and transport of water across the plant.
|
|
|
xylem is involved and it is a dead tissue.
|
Detailed explanation-1: -The root pressure is also responsible for the upward movement of water in the plants. It is mainly due to the osmotic pressure in the root cells that force the water to move upwards.
Detailed explanation-2: -As the temperature increases, transpiration will increase due to a higher concentration in sunlight and warm air. However, if temperatures remain high for long periods of time eventually leading to drought, transpiration may go down to conserve water in the plant.
Detailed explanation-3: -Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves.
Detailed explanation-4: -Complete answer:-Transpiration Pull: It is the process in which a force of pulling is produced inside the xylem tissue. This force causes the upward movement of the water column in the xylem vessels. This occurs in all higher plants and trees.
