H Bio Cell Organelle
| Term | Definition |
|---|---|
| Cells | The Basic unit of structure & function in all living things. |
| Organelles | Tiny structures inside a cell that carry out specific functions within a cell. |
| Nucleus | The information center.The “brain” of the cell.Contains the Chromatin. |
| Chromatin | Material in cells that contains DNA and carries Genetic information. It directs the functions of a cell. |
| Nuclear membrane (Nuclear Envelope) | It surrounds & protects the nucleus. |
| Nucleolus | Found inside the nucleus. It makes ribosomes. |
| Ribosomes | The site where proteins are made. |
| Golgi body | The cell’s “Mailroom”. They receive proteins and package them and distribute them to other parts of the cell. |
| Endoplasmic Reticulum | Passageways that carry proteins and other materials from one part of the cell to another.(Rough with ribosomes/smooth without |
| Mitochondria | Energy suppliers of the cell.They release energy(ATP) stored in food.Cells that need more energy have more Mitochondria. |
| Lysosome | Small round structures that contain chemicals to break down food & waste.The recycling centers of the cell. They “Clean” the cell. |
| Vacuoles | The storage rooms of the cell.Mostly contain water and food. Very Large in plants. |
| Cell Membrane (plasma biolgical,plasma membrane, biological membrane) | A protective barrier that surrounds a cell. It regulates what substances enter and leave the cell; Semi-permeable |
| Cytoplasm | A Gel-like substance found between the nucleus and cell membrane. |
| Cell Wall | Only in Plants!It is like a “Skeleton”. It is made of a non-living material called cellulose.It supports and protects. |
| Chloroplast | Only found in plants!This is where photosynthesis happens.They contain a green pigment called chlorophyll.(Light E->Chemical glucose E) |
| Chlorophyll | Captures sunlight energy and uses it to make carbohydrates (Food) for the cell. |
| Centriole | Related to the formation of spindle during mitosis(cell division) |
| Cilia | Hair like structures for movement in a proist |
| Flagella | Tail whip like structure for movement in a protist |
| Pseudo pod | False foot used for movement in a protist |
