| Term | Definition |
|---|---|
| Cell Membrane | It encloses the cell. It acts like a gatekeeper. |
| Cell Wall | Outermost structure of a cell which provides strength and support to a cell membrane. Only found in a plant cell. |
| Chloroplasts | Food for cells that are made in organelles. Only found in plant cells. |
| Chromosomes | Located in the nucleus, they contain the code that controls the cell and transmits heredity characteristics. |
| Cytoplasm | Gel-like fluid that takes up most of the space inside a cell. |
| Endoplasmic Reticulum | Structure in a cell that is invaded in making proteins and transmitting material. |
| Golgi Bodies | Cell structure that helps package/distribute products within the cell. |
| Mitochondria | Structure in the cell that transforms the energy into a form that the cells can use to carry out it's activities. |
| Nuclear Membrane | Structure that surrounds and protects the nucleus of a cell. |
| Nucleus | The control center for most of the cell's activities. |
| Ribosomes | Structure in a cell where protein are put together. |
| Vacuole | In a cell, fluid-filled structure that had waste products or substance needed in a cell. |
| Prokaryote | Single-celled organisms that have no nucleus such as bacteria. |
| Eukaryote | Multi-cellular organisms that have a nucleus. |
| Mitosis | The process of eukaryotic cell division that produces daughter cells genetically identical to each other and to the parent cell. |
| Meiosis | A type of cell division that results in two daughter cells each with half the chromosomes number of the parent cell. |
| Monomer | A simple molecule that can join together to form a macro-molecule (polymer). Building blocks of polymer. |
| Polymer | Is a substance that is built up of a number of similar molecular units that are bonded together. Polymers can be either a natural of synthetic compound. |
| Carbohydrates | Any large group of compounds (including sugar, starch, and cellulose) which contain carbon, hydrogen, and oxygen and can be broken down to release energy in the animal body. |
| Lipids | A large collection of fats, oils, waxes, and fat soluble in water and contain carbon, hydrigen, and oxygen. |
| Proteins | Composed of amino acids, and are important for structural components of the body. |
| Nucleic Acids | Macro-molecule composed of chains of monomeric nucleotides. These molecules carry genetic information, such as DNA and RNA. |
