Transpiration and transpirational pull
1.
2. Transpiration( also
known as sweating or
hyperhidrosis) is a
process similar to
evaporation.
It is the loss of water
vapour from parts
of plants, especially
in leaves but also
in stems, flowers and
roots.
3. Water is absorbed by the
roots, through the stem
and then to the leaves
where it evaporates. The
water transports the
nutrients from the soil that
the plant needs to grow.
Transpirational pull only
works in plants and trees
because of the presence
of xylem in their stem.
