  2. 2. HOW IT STARTS. Water absorption in a plant is carried by the roots. And then to the leaves.
  3. 3. 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.
  4. 4. • 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.
  5. 5. THE PROCESS; THESTEMS• 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 stem and the phloem will be on the outer side.
  6. 6. THE PROCESS; THELEAVES• Lastly, the water 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 never ends.
  7. 7. THE FLOW, INPICTURES! The Roots
  8. 8. THE FLOW, INPICTURES! The Stem
  9. 9. THE FLOW, INPICTURES! The Leaves
