Cell Parts
Parts of the cell and functions
| Term | Definition |
|---|---|
| Cell Wall | Only located in plant cells. Surrounds cell and gives the cell structure and support. |
| Cell Membrane | Surrounds the cell; acts as a barrier that allows substances to pass in and out of the cell. |
| Cytoplasm | Jelly-like substance outside of the nucleus where all of the organelles are contained. |
| Flagellum | Whip-like tail that helps unicellular organisms move. |
| Cilia | Hair-like projections that help unicellular organisms move (also located in our lungs, esophagus, and nose). |
| Ribosomes | Where protein synthesis takes place; made in the nucleolus. |
| Oral Groove | The cilia sweep food particles into this part of the paramecium before travelling to the gullet. |
| Lysosomes | Small, round vesicles that contain enzymes that digest cell nutrients. |
| Food Vacuoles | Storage pocket for food in paramecium. |
| Contractile Vacuoles | Storage pocket for water in paramecium and Euglena. |
| Smooth Endoplasmic Reticulum (ER) | Transports materials throughout the cell and produces lipids (fats). |
| Rough Endoplasmic Reticulum (ER) | Transports materials throughout the cell and produces proteins; ribosomes attach to it. |
| Golgi Bodies | Sort and package materials such as proteins and carbohydrates into vesicles to be delivered to certain parts of the cell. |
| Mitochondria | Powerhouse of the cell; produce ATP (energy) for the cell to use. |
| Chloroplast | Only found in plant cells; convert light energy of the sun into sugars that can be used by cells. |
| Vacuoles | Vesicles in the cell that store nutrients, waste, or water. |
| DNA | Contains the genetic material and information of the cell. |
| Nucleolus | Where ribosomes are made. |
| Anal pore | Pore through which all waste exits the paramecium |
