Plant & Animal Cells
| Term | Definition |
|---|---|
| Cell Membrane | Structure that controls what moves into and out of the cell. |
| Ribosomes | Found in all cells, responsible for protein synthesis. |
| Nucleus | Control center of the cell. Contains DNA. |
| Nucleolus | Dark-colored mass in the nucleus. Where ribosomes are made. |
| Endoplasmic Reticulum | -Connected to nuclear membrane - Transportation system (highway system) TWO TYPES: Smooth - No Ribosomes | Rough - ribosomes attached |
| Golgi Body (Apparatus) | Postal System/FedEx. Modifies, packages, and transports cell products to areas inside the cell or outside the cell. |
| Lysosome | "Garbage Disposal". Digests wore out. Contains digestive enzymes. |
| Vacuole | Storage site for waste, enzymes, water, etc. Large in plant cells, numerous small in animal cells. |
| Centrosome | Organelles which serve as the main microtubule organizing centers for animal cells. Made from arrangement of two barrel-shaped clusters of microtubules called "centrioles" and a complex of proteins that help additional microtubules to form. |
| Vesicle | Transport materials from one place to another. |
| Transport Vesicle | Can move molecules between locations inside the cell, e.g., hormones or neurotransmitters - from an organelle to specific sites at the cell membrane, where it locks and fuses to release its content. |
| Secretory Vesicle | A vesicle that mediates the vesicular transport of cargo. e.g., proteins from the rough endoplasmic reticulum to the Golgi apparatus. |
| Cytosol | The aqueous component of the cytoplasm of a cell, within which various organelles and particles are suspended. |
| Mitochondria | POWERHOUSE OF THE CELL. Cellular respiration occurs here: creates ENERGY for cell. |
| Chloroplast | Site of food production for plants (photosynthesis). Convert sunlight into energy. Contains chlorophyll, which makes plants green. |
| Cell Wall | Structure that helps maintain the shape and rigid structure of the cell. |
