The Cell
| Term | Definition |
|---|---|
| cell wall | rigid membrane around cell; provides shape and support |
| vacuoles | spherical storage sac for food and water |
| cell membrane | membrane surrounding the cell that allows some molecules to pass through |
| Golgi Apparatus | flattened membrane sacs for synthesis, packing and distributing. |
| Mitochondria | rod-shaped double membranous structure where cellular respiration takes place. |
| Microfilaments & Microtubules | fibers and tubes of protein that help move internal cell parts |
| Endoplasmic Reticulum | folded membranes having areas with and without ribosomes used for transport of RNA and proteins |
| Nucleolus | dense body in the nucleus; location of hereditary information (chromosomes); surrounded by nuclear envelope |
| Nuclear Envelope | double membrane that surrounds the nucleus; fused at certain points to create nuclear pores; outer membrane is continuous with the ER |
| Ribosomes | structures that manufacture proteins; found on the ER and floating in the cytoplasm |
| Centrioles (animal cell only) | short tubes necessary for cell reproduction in some cells |

| Lysosomes | spherical sac containing enzymes on the surface of some cells used for digestive functions |
| cilia (animal cells only) | short, hair-like extensions on the surface of some cells used for movement and food gathering |
| flagella (animal cell only) | long, whip-like extensions on the surface of some cells used for movement |
| Cytoplasm | jelly-like substance in the cell that contains various organelles, inclusions and the cytosol |
| Cytosol | liquid like substance that makes up part of the cytoplasm. location of several metabolic processes, make up of water, proteins dissolved ions and other smaller molecules |
