TYPES OF CELL ORGANE
The different types of cell organelles
| Term | Definition |
|---|---|
| Prokaryotes | cells that are less complex with no true nucleus or other membrane-bound organelles. Organisms within the domain bacteria and archaea have a single prokaryotic cell. |
| Eukaryotes | Eukaryotic cells contain a nucleus and membrane-bound organelles and are found in organisms such as animals, plants, fungi and protozoa. |
| Organelles | (make up the subunits of a cell) a subcellular structure that has one or more specific jobs to perform in the cell. There are numerous each with their own function. |
| Cell membrane | A large oval-shaped structure around the cell (outermost barrier of the cell). It controls what enters and leaves the cell. |
| Nucleus | Coordinates all the activities of the cell & directs cell activity. Separated from cytoplasm by nuclear membrane. Contains genetic material DNA. |
| Nuclear envelope | Membrane enclosing the nucleus. Protein-lined pores allow material to move in and out. |
| Cytoplasm | Fluid material where activities of the cell occur. The jelly-like substance also help hold the rest of the organelles in place (provides structure) |
| Nucleolus | Condensed region where ribosomes are formed/produced. |
| Ribosomes | sites of protein synthesis. Ribosomes are found in the cytoplasm and on the ER. |
| Mitochondrion | Site of cellular respiration. Mitochondria produces energy in the form of molecules through the process of cellular respiration. (power house of the cell) |
| Golgi apparatus | System of flattened membranes that process, package and store substances before their release. |
| Endoplasmic reticulum | Intracellular and intercellular transport system. Consists of flattened interconnected membranes it provides a pathway between the nucleus and the cell’s environment. |
| Vacuole | Membrane-bound sacs for storage, digestion, and waste removal. Contains water solution. |
| Lysosomes | special organelles found within the cytoplasm of animal cells. Contains digestive enzymes, instead of wasting raw material the cell recycles and reuses. It is known as the garbage disposal system of the cell. |
