The movement of water through the vascular plants, it is known as the process of transpiration.
00:08
So in transpiration, the liquid water that is dissolved with ions and other nutrients, these are drawn.
00:31
Up from the roots to the leaves of a plant.
00:44
This is the transpiration.
00:46
And this happens because of the evaporation of the water out of the leaves.
00:59
This evaporation, it pulls the water up the roots.
01:11
And here the roots, they take the water from soil.
01:22
Then these water it is drawn up the stems to the leaves.
01:36
Then here the veins of the leaves they carry the water to the leaves and from leaves.
01:50
And from leaves they again evaporates.
01:55
This is how the transpiration process takes place.
01:59
In the next question, the mechanism of transpiration, this mainly happens by the opening and the closing of the tomato.
02:22
So here these stomata, these are the minute openings that are present on the epidermis of the leaves.
02:40
And here each stoma, they consist of the two tightly specialized epiomal.
02:53
Dermal cells, these cells are known as the guard cells.
03:03
So when the gird cell there is the turgare, it is increased in the gird cells, then these results in widening of the stomatal aperture...
