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 |
