Describe the adaptations of a root hair cell for water absorption and list three forces responsible for upward water movement in plants.

Welcome back Doctor — been a while! Let's pick up where you left off. 2.1 Identify part labelled a) B: Nucleus b) D: Cell membrane 2.2 Name the: a) modified epidermal tissue responsible for the absorption of water: Root hair cell b) THREE forces that are responsible for upward movement of water from the roots to the leaves: • Transpiration pull • Capillary action • Root pressure 2.3 Explain THREE ways in which the root hair cell is suited for the absorption of water • The root hair cell has a long, thin extension, which significantly increases its surface area for water absorption from the soil. • It has a thin cell wall and cell membrane, allowing for a short diffusion distance for water to move into the cell. • The cell contains a large central vacuole with a high concentration of dissolved solutes, creating a lower water potential inside the cell than in the surrounding soil, which drives water absorption by osmosis. 2.4 Tabulate ONE structural difference in relation to permeability of parts A and C | Part | Permeability | | :--- | :----------- | | A (Vacuole membrane/Tonoplast) | Selectively permeable | | C (Cell wall) | Fully permeable | Send me the next one 📸
