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.Know More
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 human genome present in the nucleus of nearly all cells within the body is composed of 3.2 billion base pairs. If unwound, this DNA would stretch to about 6 feet.Full Answer >
Although an animal cell has life and a car is lifeless, the two have some structural and functional similarities. Both a cell and a car move, are enclosed, have storage functionality and have facilities for moving fuel or nutrients.Full Answer >
In an animal cell, the cytoplasm is a semi-liquid substance that holds all the cell's organelles except the nucleus. It also acts as a repository for amino acids, sugars and other important nutrients used in the regular life of the cell. Finally, the cytoplasm stores a cell's waste until it is flushed from the cell.Full Answer >
The nuclear envelope controls the flow of information into and out of the nucleus. It is a porous double membrane that allows the free passage of water, ATP and other small molecules. It regulates the passage of macromolecules, which are much larger, and these are the molecules that carry information.Full Answer >
