Animal cells are eukaryotic cells, or cells that contain a membrane-bound nucleus. The nucleus holds the DNA of the cell that provides the cell with instructions for life.
In an animal, the cells go through constant mitosis to divide and multiply. This works to guarantee that offspring are genetically identical to the parents. Animal cells also undergo meiosis to ensure the formation of haploid cells. Haploid cells form either eggs or sperm, and these work to form a new diploid cell when one egg and one sperm meet for fertilization. The process of mitosis comes in again to divide the fertilized cell for new organism formation.Learn More
Animal cells do not contain cell walls because cell walls prevent specialization, and individual animal cells do not need protection from the outside environment. The evolution of cells without walls also meant they could connect together, which led to animals becoming the most complex organisms on Earth.Full Answer >
Animal cells and plant cells have very different mechanisms of mitosis. This is mainly due to the structural makeup of the different types of cells. For example, the cell wall affects how plant cells undergo mitosis.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 >
Prokaryotic cells are simpler than eukaryotic cells. Eukaryotes have a nucleus and organelles while prokaryotes do not. Both types of cells have a plasma membrane and contain cytoplasm.Full Answer >
