Define the term specialised cell?
Answers:
Early embryonic cells are meristematic ("stem") and not specialized to do anything in particular. As the embryo develops these cells specialize to perform various specific or specialized functions. Examples: Muscle cells-contraction/movement ; nerve cells-carry impulses ; epidermal cells-covering ; gland cells-secretions, etc.
There are several theories as to how these unspecialized cells specialize (or differentiate).
a cell that has a specific function that only that cell can execute.
example: red bloodcells.
A cell in which only a certain combination of genes can be activated by the stimulation of its environment.It has its own shape,size,weight,epitores (that is receptors),different chemical synthesis,abilities, and of course funtion.It is also divided in a distinctive way (meaning period).
A cell that is adapted to carry out its functions. e.g. red blood cells have no nucleus, and a large surface area so they can transport more oxygen round the body.
A specialised cell has a specific function within the organism and is any cell which does not fall into a wider category of cell types.
The cell that can only do special tasks. Eg. Red blood cell
A specialised cell is a cell which has a specific shape/structure to enable it to carry out a specific function within the living organism e.g. a root hair cell from a plant root has an extended appendage with an extended vacuole inside to provide a larger surface area to absorb water and minerals from the soil.
always speacial
A specialised cell is a cell that is designed to do a particular job in an organism, an example of this is a sperm cell, egg cell, the palisade cell which is used for photosynthesis, the root hair cell, etc.
