Animal cells function in a variety of ways, depending on the type of cell they are, but common cells perform functions such as digestion, support and nerve transmission. There are a number of different types of cells in every animal, though most animals have similar types of cells. Cell function influences the shape, size and character of the cells in animal bodies.Continue Reading
Common types of cells that many animals have include nerve cells, bone cells, skin cells, stomach cells, liver cells, blood cells and hair cells. However, not all animals have all of the various cell types, as reptiles, for instance, do not have hair cells. However, cells that make blood, nerves and bones are nearly ubiquitous.
Cells have a variety of functions they perform. Red blood cells carry oxygen through the body. Nerve cells, also called neurons, transmit electric impulses from the brain to the rest of the body. Skin cells combine to form a protective barrier that protects the organism.
Animals also produce sex cells, called gametes. Gametes take the form of sperm or eggs, and they feature half of the genetic complement of the parents. When gametes combine, they form a unique individual with a full DNA strand.Learn more about Cells
The main function of the cell body of a neuron is to integrate synaptic information and transmit this information to other cells via the axon. The cell body also completes a variety of biochemical processes to keep the neuron functioning properly.Full Answer >
Prokaryotic cells are single cells that evolved before eukaryotes, which are organisms whose cells contain nuclei and organelles. A prokaryotic cell has no true nucleus or membrane-bound structures called organelles. Prokaryotic cells are usually bacterial species.Full Answer >
A composite cell is any one of a collection of different types of cells that all have the same general chemical makeup that perform the same functions. Because many cells are very similar to one another in these ways, it is possible to generalize them all as composite cells.Full Answer >
RNA is important to cells because it relays information encoded in DNA to tiny organs within the cell, called ribosomes, which produce protein according to the RNA's instructions. RNA is thus vital to the basic functioning of the cell.Full Answer >
