| eukaryotic cells | cells with a nucleus including plants and animals |
| cell wall | a structure around plant cells that gives shape, support, and protection |
| cell membrane | a protective barrier that controls what enters and leaves the cell |
| cytoskeleton | a web of proteins in the cytoplasm that gives the cell membrane shape |
| nucleus | the brain of the cell that controls all cell activities |
| DNA | genetic material found in the nucleus |
| nucleolus | a dark area inside the nucleus where ribosomes are made |
| ribosomes | the smallest organelle; maker of proteins including amino acids |
| endoplasmic reticulum | a maze of passageways which delivers proteins around the cell; can be rough or smooth |
| rough ER | covered in ribosomes |
| smooth ER | maker of lipids |
| mitochondria | the main power source of the cells; breaks down sugar to produce energy |
| ATP | a substance that stores energy needed to do work |
| chloroplasts | green organelles found in plant cells in which photosynthesis takes place |
| photosynthesis | process by which plants use light to make food by changing carbon dioxide and water into sugar and oxygen |
| Golgi complex | an organelle (flattened collection of tubes) that packages and distributes proteins |
| vesicle | a bubble that surrounds material to be moved in/out of a cell |
| lysosomes | an organelle found mainly in animals that contains enzymes responsible for digestion in a cell |
| vacuoles | areas in a cell that store water |
| plant & animal cell differences | only plants have cells walls, chloroplasts, large vacuoles, and a rectangular shape |
