|---|---|
| Cytoplams | all of the material inside the plasma membrane of a cell (including organelles) |
| Eukaryote | all of the material inside the plasma membrane of a cell (including organelles) |
| Eukaryote cell | cell that contains a nucleus and other organelles |
| Nucleus | organelle inside eukaryotic cells that contains most of the cells DNA and acts as the control center of the |

| Pasma membrane | thin coat of lipids (phospholipids) that surrounds and encloses a cell |
| Prokaryote | single-celled organism that lacks a nucleus |
| Prokaryote cell | cell without a nucleus that is found in single-celled organisms |

| Virus | tiny, nonliving particle that contains DNA but lacks other characteristic of living cells |
| ATP | energy-carrying molecule that cells use to power their metabolic processes |
| Cell wall | rigid layer that surrounds the plasma membrane of a plant cell and helps supports and protect the cell |
| Central vacuole | large sac-like organelle in plant cells that stores substances such as water and helps keep plant |
| Chloroplast | organelle in the cells of plant and algae where photosynthesis takes place |
| Cytoskeleton | structure of filaments and tubules in the cytoplasm that provides a cell with and internal framework |
| Endoplasmic riticulum | organelle in the eukaryotic cells that helps make and transport proteins |
| Endosymbiotic theory | theory that eukaryotic organelles such as mitochondria evolved from ancient, free-living prokaryotes |
| Golgi apparatus | organelle in eukaryotic cells that processes proteins and prepares them for use both inside and outside the cell |
| Mitochondria | organelle in eukaryotic cells that makes energy available to the cell in the form of APT molecules |
