Plant Transport
Traspiration
Transpiration process
- water and mineral ions from the soil move into the plant through osmosis. Root hair cells ensure that this water osmoses quickly. The mineral ions are able to move into root hair cells through active transport, which is the movement of molecules across a cell membrane from a region of lower to higher concentration.
- the water then moves into the root cortex cells, which is located in the middle of the vascular bundle.
This is not only because the root cells do not need to maintain a rigid structure but also to prevent the root from coming out of the soil.
- Xylem vessels then collect the water from the root cortex cells and transport it up the plant’s stem. Vascular bundles in the stem are located closer to the epidermis in order to keep the stem’s rigid shape.
- When the water reaches a leaf, it osmoses out of the xylem cells and into the leaf’s mesophyll cells. Most of the water then evaporates from the surfaces of the mesophyll cells into the air space between the cells. This water vapour diffuses out of the stomata.
