 Welcome to this module on Identifying Eukaryotic Animal Cell Organaels. This is a drawing of a generic eukaryotic animal cell. The Endoplasmic Reticulum RER, rough endoplasmic reticulum, is important in transporting proteins made by ribosomes on the RER. SER, smooth endoplasmic reticulum, is important in lipid synthesis. Ribosomes are small, naked, non-membrane bound particles made of R, RNA, and proteins. They're the cell's protein factories and are found on RER and scattered in the cytoplasm as polyribosomes. The Golgi apparatus is a stack of interconnected, flattened, membranous sacs that can synthesize, package, and release molecules to the outside of a cell via secretory vesicles. Mitochondria These organelles have two layers of membranes. Energy from glucose and other nutrients is transferred to the ATP through a series of chemical reactions in the presence of oxygen. Lysozomes These vesicles contain hydrolytic enzymes that decompose or hydrolyze biomolecules. They are made by the Golgi complex and their nicknames are suicide bags and garbage disposals. Paroxysomes These are the most abundant in the liver and kidney cells. They contain enzymes for detoxification of many biochemicals including alcohol. Centrosome The centrosome contains two hollow cylindrical centrioles which are perpendicular to each other. They play a crucial role in mitotic division of eukaryotic animal cells. Nucleus The nucleus is the double layered control center of the cell. It contains chromatin, genetic material, and the nucleolus which is the site of ribosome production. Cell membrane The cell membrane is mainly composed of lipids and proteins. Its framework consists of a double layer of phospholipids. Plants, animals, fungi, and protista are composed of eukaryotic cells. In these cells, organelles create compartments where specific biochemical reactions can occur. Congratulations! You have completed identifying eukaryotic animal cell organelles.
