| Term | Definition |
|---|
| Plasma Membrane | Cell membrane acts as a selective barrier, thereby regulating the cell's chemical composition. Composed of a phospholipid bilayer within which proteins are embeded. |
| Cytoplasm | Cellular region between nuclear and plasma membranes. Contains cytosol, inclusions and organelles |
| Mitochondria | Rodlike organelle. Powerhouse. Site of ATP synthesis (Energy) |
| Ribosomes | Dense particle composed of RNA and protein. Site of protein synthesis. |
| Endoplasmic reticulum | Membrane system found in a cell's cytoplasm Assists in the production, processing, and transport of proteins and lipids. Can be rough (Ribosome studded) or smooth(complex functions) |
| Golgi apparatus | Stack of smooth membrane sacs close to nucleus. Modifies and packages protein for export from cell. |
| Lysosomes | Membranous sacs. Site of intracellular digestion. Contains enzymes. |
| Cytoskeleton | Protein fibers that hold the cell together and keep its shape, Aids in intracellular and extracellular movement. Consists of microfilaments, microtubules and intermediate filaments. |
| Nucleus | Largest Organelle - control centre of cell. Contains DNA and RNA and has its own membrane. |
| Centrioles | Paired cylindrical bodies composed of microtubules. Involved in Mitosis |
| Cillia | Short, hair like,plasma membrane extensions made of microtubules. Move substances in one direction across cell membrane |
| Flagella | Single, long whip-like projections that move cells eg tails in spermatazoa. Formed of microtubules on cell surface. |
