WebFunction: absorption of water and mineral ions from soil Adaptations: Root hair to increase surface area (SA) so the rate of water uptake by osmosis is greater (can absorb more water and ions than if SA were lower) Thinner walls than other plant cells so that water can move through easily (due to shorter diffusion distance) WebSpecialized Cells Cell functions and life processes. Some cells in multicellular organisms are modified to carry out a particular function, such as transporting a certain substance or executing a specific task. These cells are called specialized cells. ... Root hair cells, palisade cells, and guard cells are examples of specialized plant cells ...

WebRoot hair cells are specialised to allow plants to absorb more water and let a plant absorb the minerals it needs to keep alive. Xylem and Phloem cells are used by the plant to transport minerals, sugar and water to other parts of the plant. Xylem cells The xylem is specialised to transport water up the stem of a plant and into the leaves. WebWhat drives cell differentiation is the control of gene expression. Specialised cells are formed from the differentiation of stem cells. Stem cells have the potential to give rise to all other cell types with specific shapes and functions. Some examples of specialised cells are red blood cells, muscle cells, root hair cells, xylem and phloem cells. WebThe human body contains hundred of different types of cells that each serve a different purpose. Each cell has adaptations that allow it to work effectively within living things. Once students have mastered basic cells, they should move on to specialized cells and their specific functions. criticas serie la promesse
