| Peroxisomes | Membranous sacs containing powerful oxidase enzymes that use molecular oxygen to detoxify a number of harmful or poisonous substances. |
| Catalase | Enzyme that converts excess hydrogen perioxide to water |
| Cytoskeleton | Acts as a cell's "bones & muscles" by furnishing an internal framework that determines cell shape. Supports other organelles, and provides the machinery needed for intracellular transport and various types or cellular movements. |
| Intermediate Filaments | Stable ropelike filaments gelp form desmosomes and provide internal guy wires to resist pulling forces on the cell. |
| Microfilaments | Mostly involved in cell motility and producing changes in cell shape. |
| Actin | One of the three major components of the cytoskeleton which is part of the contractile apparatus in muscle cells |
| Myosin | Comprise a superfamily of ATP-dependent proteins and are best known for their role in muscle contraction. |
| Microtubles | Determine the overall shape of the cell in the distribution of organelles. |
| Centrioles | Rod-shaped bodies that lie at right angles to each other. Internally they are made up of fine microtubles . During cell division, centrioles direct the formation of mitotic spindle fibers. |
| Cilia | Whiplike cellular extensions that move substances along the cell surface. |
| Flagella | Long projections formed by the centrioles |
| Fibroblasts | Elongated shaped cell that lies along cable-like fibers that it secretes. It has an abundant ER and a large Golgi apparatus to make and secrete the protein building blocks of fibers. |
| Erythrocyte | Red blood cell that carries oxygen in the blood stream. |
| Epithelial Cell | Honeycomb shaped cells which allows cells to pack together in sheets which help it in resisting tearing when pulled or rubbed. |
| Skeletal Muscle Cells | Elongated cells filled with abundant contractile filaments, therefore they can shorten forcefully and move the bone. |
| Smooth Muscle Cells | Can change the size of internal organs. |
| Fat Cell | Huge spherical shaped cell that is produced by a large lipid droplet in its cytoplasm. Store nutrients |
| Macrophage | Phagocytic Cell. Extends long pseudopods or "false feet" to crawl throgh tissue to reach infection sites.Fight diseases, such as lysosomes. |
| Oocyte | Female cell that is the largest in the body and contains several copies of all organelles, for distribution of the daughter cells that arise when the fertilized egg develops to become an embryo. |
| Sperm | Male cell that is long and streamlined, built for swimming to the egg for fertilization. Its flagellum acts as a motile whip to propel the sperm. |
