WebPlants can only absorb soluble minerals (those that can dissolve in water). They absorb minerals dissolved in solution from the soil through their root hair cells. However, the concentration of minerals in the soil is very low. Active transport – Higher tier only. Minerals cannot be absorbed by osmosis because this is the movement of water only.

WebRoot hair cells. The root hair cells are where most water absorption happens. They are long and thin so they can penetrate between soil particles, and they have a large surface area for absorption of water through osmosis. Water passes from the soil water to the root hair cell’s cytoplasm by osmosis. This happens because the soil water has a ...

WebRoot hair cells are adapted for the efficient uptake of water (by osmosis) and mineral ions (by active transport) \t Root hairs are single-celled extensions of epidermis cells in the root WebThe root hair is an extension of the cytoplasm, increasing the surface area of the cell in contact with the soil to maximise absorption of water and minerals Function: absorption of water and mineral ions from soil Adaptations:
WebRoot hair cells are responsible for the uptake of nutrients from the soil via the process of active transport. Root hair cells contain high concentrations of mitochondria to provide the energy needed in active transport.
