| A | B |
|---|
| cell membrane | present around ALL cells;allows only certain substances to enter and leave; gateway |
| cell wall | encloses the cell membrane of plant cells; protects and supports plant cells |
| chloroplasts | contain the green liquid pigment chlorophyll; capture sunlight for making food in plant cells |
| chromosomes | location of instructions for all cell activities; directs cell activities; made of DNA |
| cytoplasm | jelly-like material in which cell parts constantly move; area outside the nucleus of a eukaryotic cell |
| endoplasmic reticulum (ER) | "tunnels" that transport material through the cytoplasm |
| eukaryotic | cells with membrane-bound structures |
| Golgi bodies | package and move proteins outside the cell |
| lysosomes | contain digestive enzymes that break down food particles and waste |
| mitochondria | "powerhouses" of cells; produce most of the energy of a cell |
| nuclear membrane | surrounds the nucleus; allows substances to enter and leave the nucleus |
| nucleus | controls all of the functions of plant and animal cells; control center |
| prokaryotic | describes a cell that does not have a nucleus or anyother membrane-covered organelles; bacteria and some algae |
| ribosomes | tiny structures in the cytoplasm where proteins are made |
| vacuoles | mostly in plant cells; store water and nutrients for the cell; very large in plant cells; "storage tanks" |
