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 nucleolus contains all of the information needed for DNA replication, flow of proteins and RNA, all while controlling the synthesis of protein and cell replication. The nucleolus has several parts: the nuclear envelope, the chromatin and the actual DNA.Full Answer >
Chromatin forms chromosomes during cell division, packages DNA, reduces DNA volume, protects DNA from damage, and controls gene expression and DNA replication. Chromatin is a substance located in the nucleus of plant and animal cells consisting of RNA, DNA and other proteins.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 >
Animal cells aren't all shaped the same way; the shape of a specific animal cell depends on its function and where it is in the body. Unlike plant cells, animal cells do not have rigid cell walls that limit them to a rectangular shape.Full Answer >
