Transpiration is the process by which water absorbed by plant roots is evaporated from leaves into the atmosphere. It allows plants to receive nutrients by absorbing more water through their roots, maintaining a constant water flow. Transpiration occurs through the xylem tubes in plant stems, with water evaporating from leaf pores and forming droplets that create a transpirational pull moving water up from the roots.

2. What Is
Transpiration?
 Transpiration is the
process whereby
water, that is absorbed
by plants, usually
through the roots, are
evaporated into the
atmosphere from the
leaves of the plant.

3. Transpiration plays a very important role as it allows the
plant to receive key nutrients and minerals. By this
process, the plant will be able to absorb more water
from its roots, allowing a constant flow of water to take
place.

4. Transpiration pull only works
in plants and trees because
their stems contain bundles
of many very fine tubes,
made of woody material,
called xylem.

5. The transpiration process begins at the
surface of the leaves of the plant or tree.
Water continually evaporates from the
pores of the leaf and is lost into the
atmosphere. This evaporation causes
million of minutely small droplets of water
to form inside the pores. Thus, this causes
transpirational pull.
