Question 4
How are water and minerals transported in plants?

Answer 1

1. Water and nutrients are carried from the soil to the leaves via xylem cells in plants.
2. Roots, stems, and leaves all include xylem cells that are linked to form a conducting channel that reaches all parts of the plant body.
3. Ions are taken in by the root cells from the soil.
4. This results in a differential in ion concentrations between roots and soil.
5. As a result, there is a constant flow of water into the xylem.
6. Osmosis causes the flow of water and minerals from one cell to the next, creating an osmotic pressure.
7. The constant loss of water is caused by transpiration.
8. Water is pushed into the xylem cells of roots due to a suction pressure created by transpiration.
9. At night, root pressure has a greater impact on plant movement, but during the day, transpiration pull becomes the primary driving factor.
