| Term | Definition |
|---|---|
| cytoplasm | refers to all of the cellular material inside the plasma membrane. |
| eukaryote | Organisms with eukaryotic cells. |
| eukaryotic cell | are cells that contain a nucleus. |
| nucleus | a structure in the cytoplasm that is surrounded by a membrane (the nuclear membrane) and contains DNA. |
| organelle | is a structure within the cytoplasm that performs a specific job in the cell. |
| plasma membrane | is a thin coat of lipids that surrounds a cell. |
| prokaryote | Organisms with prokaryotic cells |
| prokaryotic cell | are cells without a nucleus. |
| ribosome | are structures in the cytoplasm where proteins are made. |
| virus | are tiny particles that may cause disease |
| ATP | an energy-carrying molecule that is used almost universally inside cells for energy. |
| cell wall | is a rigid layer that surrounds the plasma membrane of a plant cell. |
| central vacuole | this vacuole can make up as much as 90% of the cells volume. |
| chloroplast | are plastids that contain the green pigment chlorophyll. |
| cytoskeleton | Crisscrossing the cytoplasm |
| endoplasmic reticulum | is a organelle that helps make and transport proteins and lipids. |
| endosymbiotic theory | larger prokaryotic cells, and the two organisms evolved a symbiotic relationship that benefited both of them. |
| Golgi apparatus | is a large organelle that processes proteins and prepares them for use both inside and outside the cell. |
| mitochondria | is an organelle that makes energy available to the cell. |
| phospholipid bilayer | The phospholipid in the plasma membrane are arranged in two layers. |
| vacuoles | sac-like organelles |
| vesicles | are much smaller than vacuoles and have a variety of functions. |
