|---|
| Nucleus | Control center of the cell |
| Nucleus | Ribosomes are formed here |
| Rough Endoplasmic Reticulum | connected to the nuclear envelope; produces proteins for export; studded with ribosomes |
| Nuclear Envelope | Membrane that surrounds and protects the NUCLEUS |
| Ribosomes | produce proteins, can be free or attached |
| Smooth Endoplasmic Reticulum | detoxifies and produces cell membrane components |
| Golgi Apparatus | Collects, Packages and Modifies cell products |
| Cell Membrane | Membrane that surrounds and protects the entire cell |
| Cytoplasm | The jelly-like interior of the cell |
| Transport Vesicle | Small membrane-bound spheres which move cell products around inside the cell |
| Cilia | hair-like projections on the outside of the cell membrane; movement |
| Flagella | whip-like tail on the outisde of the cell; movement |
| Mitochondria | converts sugars into cell-energy (ATP); in both animal and plant cells |
| Chloroplast | transfers the energy from the sun into high-energy sugars (food) |
| Cytoskeleton | provides shape and structure to the cell; made up of microtubules, microfilaments & intermediate filaments |
| Vacuole | stores water and cell products; larger in plants than in animals |
| Lysosome | digests and recycles food, worn-out organelles and invaders; contains digestive enzymes. |
| Centriole | involved in cell division; only in animal cells |
| Chromatin | DNA + protein fibers; located in the nucleus |
