| 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 |
| organ |
group of two or more tissues that perform an activity together. |
| organ system |
group of organs that work together to perform a major life function |
| organelle |
internal membrane-bound structures in a cell. |
| plasma membrane |
serves as a boundary between the cell and its environment, allowing nutients to enter and wastes to exit. |
| plastid |
plant organelles that contain pigments. they may store starch and lipids. |
| prokaryote |
a cell lacking a true nucleus |
| ribosome |
eukaryotic organelles involved in protein synthesis |
| tissue |
group of cells that function together to carry out an activity |
| unicellular |
organism that carries out all its life functions within a sincle cell. |
| vacuole |
membrane-bound, fluid-filled space within the cytoplasm which temporarily stores food, enzymes, and wastes. |
