Cells Unit
| Term | Definition |
|---|---|
| Infectious Disease | A disease that is passed from one organism to another |
| Vector | An organism that spreads disease causing microbes from one host to another without getting itself sick. |
| Carrier | A person who can spread disease. This term is usually applied to people while vector is used to describe other organisms usually animals. |
| Microbe | A microscopic organism or a virus. |
| Cell | The smallest structural unit enclosed by a membrane, that makes up all living organisms. |
| Cell Theory | The theory that all living organisms are made up of cells, cells are the basic unit of structure and functioning in living organisms, and new cells are made from pre-existing cells. This theory is supported by the Cell Principle. |
| Germ Theory of Disease | The theory that microbes can cause infectious disease. |
| Multicelluar organism | An organism made up of many cells (two or more) |
| Uni- Celluar organism | An organism made up of one cell. |
| Matter | The stuff that makes up all living and non-living objects. Carbon dioxide, oxygen, and sugars are all examples. |
| Energy | The ability to cause an object to change move or work. |
| Celluar Resperation | A series of chemical reactions in a cell that break down sugars and release energy. |
| Indicator | A chemical that indicates the presence absence or concentration of a particular substance. |
| Bacteria | single celled organisms that do not have a neculus or other membrane- bound organelles. |
| Protist | An organism made up of a single cell or many cells with a neculus and that is not an animal, plant or fungus. |
| Virus | A microbe that is not made of cells and cannot grow or produce outside of a living cell. |
| Function | This specializes activities performed by a system, organ, body part, object or device. |
| Structure | The parts of an object or system, including what they are made of, their shapes, and their arrangement. |
| Organelle | Cell structures, often surrounded by a separate membrane, that perform a specific function. |
| Cytoplasm | Jelly like substance within the cell membrane. |
| Lysosome | Sac filled with digestive chemicals. |
| Mitochondria | Structures that convert nutrients to energy. |
| Centriole | Structure that organizes the motion of chromosomes. |
| Endoplasmic Reticulum | Passageways were chemicals are made. |
| Vacuole | Sac that stores water, nutrients, or waste products. |
| Cell Membrane | Membrane that surrounds and protects the cell. |
| Nucleus | Structure that contains DNA and regulates genes. |
| Cytoskeleton | Tubules and filaments that give the cell it's shape. |
| Evidence | Data that supports a claim. |
| Trade-Off | A desirable outcome given up to get another desirable outcome. |
| Pattern | Something that happens in a repeated and predictable way. |
| Ribosome | Small structure that synthesizes proteins. |
| Nuclear membrane | Membrane that protects the nucleus. |
| Golgi apparatus | Stack of membranes that packages chemicals. |
| Vesicle | Package created by the Golgi Apparatus |
| Nucleolus | Tubules and filaments that give the cell it's shape. |
| Capsule (Bacteria) | Outermost layer of the cell that provides protection. |
| Nucleoid (Bacteria) | Region inside the cell that contains genetic material but is not sorrounded by a nuclear membrane. |
| Plasmid (Bacteria) | Circular piece of genetic material. |
| Flagellum (Bacteria) | Hair like structure that the cell uses for movement. |
| Pilus (Bacteria) | Hair- like structures that attaches the cell to the surface and can transfer genetic material from one cell to another. |
