What are specialisation cells:
Specialised cells are those with distinctive structures and have unique functions in the body. They work together in groups to form different tissue types, for example in nerves or muscles. These tissues form organs, which support bodily functions.
Types of specialisation cells:
Ciliated cells:
Ciliated cells are adapted in the respiratory tract to form an epithelial lining of coordinated metachronal ciliary activity that provides the propelling force for the transport of mucus along the airways.
2. Root hair cell: Root hairs are the hair-like tubular extensions of a plant root that increase the surface area of the root. The function of the root hairs is to absorb water and minerals and transport it through the plant.
3. Nerve cells: A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.
