-Carrying dissolve ions -Keeping cells rigid -Cooling the leaves (when it evaporates from them) -Photosythesis
1 of 6
What are the adaptations of Root Hair Cell?
The shape increases surface are which helps to absorb more mineral ions -Has thin cell wall making it easy for mineral and water to pass through
2 of 6
Explain how diffusion in plants pathway work?
Cell wall have an open structure allowing water particles to move through diffusion towards the middle of the plant
3 of 6
Explain how osmosis in plants pathway work?
Cell membrane are semi-permeable membrane and so water passes into the cytoplasm of root hair cell by osmosis
4 of 6
Why do plans need nitrates?
To make proteins
5 of 6
Describe the process of Active transport in the plant?
Concentration of ions inside a root hair cell is greter than the soil.Mineral ions cannot move aginst concentration gradient so proteins in the cell membrane pump ions in to the cell
