| lysosome | a membrane-bound organelle that digests and recycles cell wastes or foreign invaders. |
| microfilament | thin, solid protein fibers that play a role in cell structure or movement |
| mitochondria | eukaryotic, membrane-bound organelle in which food molecules are broken down to produce energy-ATP |
| multicellular | organisms composed of many cells and are highly specialized. |
| nucleolus | dark-staining area within the nucleus where ribosomes are made |
| nucleus | largest membrane-bound organelle within the cell that contains DNA and manages the cell's functions |
