Ciliated Epithelium. Cell Specialization: All living organisms are composed of one or more cells – this statement is probably one of the most important principles of the Cell Theory by Theodor Schwann and Matthias Schleiden.. Specialised animal cells. Plant Cell Specialisation In this GCSE Biology video we look at plant cell specialisation. What organelles are found in plant cells, but not in animal cells? Root Hair Cells are used to help the plant take up water and dissolved mineral ions. Long and tube-like hollow vessels to carry the water. It has thin walls so as not to restrict the movement of water. 2) Each cell has lots of mitochondria that produce ATP which fuel the active transport of water into the root hair cell. Root hair cells These cells are responsible for absorbing water (for photosynthesis) from soil around the roots. This allows more active transport of mineral ions to take place so the plant is able to take in as many important mineral ions as possible e.g. The nerve cell is covered with a fatty sheath, which insulates the nerve cell and speeds up the nerve impulse. Another adaptation that they have is root hair cells have a large permanent vacuole. It has thin walls so as not to restrict the movement of water. The role of root hair cells is to absorb water and mineral ions. • root hair cells, xylem and phloem cells in plants. Root hair cells The root hairs are where most water absorption happens. Their role is to absorb water and minerals in the soil. Test. A root hair cell has a long and narrow protrusion. Wall nearest the soil has a long 'finger-like' projection with very thin walls into the soil. Both plants and animals have cells that are specialised. This allows the root hair coverage to remain the same despite root hairs constantly dying.
