One example of cell specialization is the role of the white blood cell in immune function. Cell specialization occurs when a cell contains certain organelles or structures that allow it to perform a specific set of functions in an organism.
Other types of cells that have specialized functions include nerve cells and fat cells. The function of nerve cells is to transport information to and from the brain and spinal cord in relation to sensory and other experiences related to the central nervous system. Nerve cells may also be referred to as neurons. Fat cells assist in cushioning the body and serve as a reservoir for energy.
When several specialized cells are grouped together for a specific function, they make up tissues. Those tissues are further synthesized to form organs. Specialized cells have unique structures to assist them in their functions. However, all cells have some organelles that are common to the function of a living cell.
Specialized cells provide an advantage to the organism. They allow a division of labor of activities within the body. Because some cells are able to perform some functions, there is an increased efficiency in metabolism and other activities necessary for the organism to survive.Learn More
In an embryo, one cell becomes a brain cell and another a skin cell through the process called cell differentiation, which involves changes in gene expression. The genome stays the same in each specialized cell, while each cell has a different structure and functions.Full Answer >
An example of a symbiotic relationship is that which exists between a parasitic worm and the horse within which it lives. In this specific case, the type of symbiotic relationship that is occurring is known as parasitism. One organism, the worm, benefits from the relationship, while the other, the horse, is harmed.Full Answer >
Cytoplasm's main function within a cell is to act as the medium of suspension for its internal structures. These internal structures are called organelles and perform important functions like cellular respiration. The organelles themselves are not naturally buoyant, so protein filaments aid in keeping them afloat throughout the cell.Full Answer >
A cell is like a city because it has walls, a transportation system, streets, a recycling center, a power source and a library. Cells also have factories and industrial parks.Full Answer >
