HOW IT STARTS.Water absorption in a plant is
carried by the roots.
And then to the leaves.

THE PROCESS; THE ROOTS Water absorption is carried
by the younger part of roots.
Which are the root hairs. Water in the soil spaces is
taken into the root hairs by the process of osmosis, there being a higher water concentration outside than within the root hair cells.
Here’s is an example of a root hair cell.

• Once inside the root hair, the water needs to be transferred to the xylem, the vascular tissue involved in water transport through the plant.
• Xylem vessels are long, narrow, hollow tubes containing no living material and are strengthen with bands of lignin.

THE PROCESS; THE STEMS• The water moves through the roots
and into the stems.• The xylem will be brought through the
stems by sieve plates and by only in one way.
• As you can see, the xylem will always be on the central side of the stemcentral side of the stem and the phloem will be on the outer sideouter side.

THE PROCESS; THE LEAVES• Lastly, the water travelswater travels to the
leaves.• The water then either moves out of
the plant through the stomata. • This loss of water from the xylem at
the far end allows water flow up the xylem tubes, creating continuous water movement hence the cycle cycle never endsnever ends.
• Lastly, the stomata can close if water is limiting. water is limiting.
