## Specialisation in plant cells - **Specialised cells:** - Suited to its particular function. - cell differentiation. - Waxy cuticle layer-protects plants epidermic cells - Layers could be different - Many don't contain chloroplasts. - Guard cells-open and close stomata. - Enzymes to digest insects. - Palisade layer has loads of chloroplasts to absorb sunlight ### **Roots (Root hair) cells** - Plant absorbs water from the soil through osmosis - Root hair cells are adapted by having a large surface area - Loads of mitochondria inside for transport of water and minerals ### **Xylem** - Transports water and solutes from roots to the leaves. - This is called transpiration. - Contains no cytoplasm or nucleus - Made from dead cells. - One way only, up. - No end walls between cells. - Thick walls stiffened with lignin.
