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 in 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 >
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 >
One way to make an animal cell project is to use gelatin and various types of candy to represent the parts of the cell. Mix the gelatin and allow it to firm up slightly, then add the different candy representations of each cell part. For easier identification, make a reference sheet showing what part of the cell is represented by each piece of candy.Full Answer >
Animal cells have many distinct characteristics when compared to plant cells, including their varied shapes, their many types of organelles, their centrioles, cilia and lysosomes, and their cell-to-cell junctions. Animal cells also lack chloroplasts and cell walls, which are found in plant cells.Full Answer >
