Life is theorized to have begun with single celled prokaryotic organisms millions of years ago. Through emdosymbiosis these cells then became eukaryotic, which is what an animal cell is today. There are many different parts and organelles of an animal cell which is why a 3D diagram or model of an animal cell is enormously beneficial when it comes to teaching students about the functions of the
. cell as a whole.Each cell has a nucleus, therein is where the genetic information for the cell is stored. Another important component of an animal cell is the rough endoplasmic reticulum. These are lined with ribosomes which synthesize various proteins that are needed by the cell. Ribosomes are created inside the nucleus by an organelle known as the nucleolus. The mitochondria is another very important constituent of an animal cell. These organelles are responsible for producing the energy a cell needs. Many college and university students learning about biology must learn about the Krebs cycle, which is the process by which chemicals used for energy are synthesized inside the mitochondria. The cell in its entirety is enclosed within the cell membrane. The cell membrane regulates the passing of materials to and from the cell. To help maintain its desired shape, the cell relies on the cytoskeleton. Cells rely on peroxisomes for protection from toxic byproducts such as hydrogen peroxide. These organelles are easy to remember if one makes the connection to peroxide in the name.There are several components of other types of cells that are not present in animal cells. One example of this is the cell wall. Plant cells have cell walls which are usually made of cellulose. Chloroplasts are another component of a plant cell that is not present in an animal cell. These are responsible for creating the Chlorophyll that plants need.
