| A | B |
|---|
| Prokaryotic (prokaryote) | a cell that lacks a nucleus and other membrane bound structures; example bacteria |
| Eukaryotic (eukaryote) | a cell that has a nucleus and other membrane bound structures; examples fungi, plants, animals, protists |
| Unicellular | organism made of one cell |
| Muticellular | organism made of more than one cell |
| Cell Theory | all living things are composed of cells; cells are the basic unit of structure and function; cells come only from existing cells |
| Cell membrane (plasma membrane) | outer boundary of cells; regulates what enters and leaves a cell |
| Cytoplasm | contains water and salts, surrounds cell organelles |
| Nucleus | directs the activities of a cell; surrounded by a membrane |
| Selectively Permeable Membrane | barrier that selects what may enter and leave a cell |
| Ribosomes | most numerous organelle in cell; where proteins are made (protein synthesis) |
| Endoplasmic reticulum | a membrane system of folds and tunnels; called ER; ribosomes may be attached to it |
| Golgi Apparatus | the processing, packaging, and secreting organelle of the cell; called the “UPS” of cell |
| Mitochondria | site of cell respiration; produces ATP; has DNA |
| Chloroplast | site of photosynthesis; produces glucose; contains chlorophyll; unique to plant cells |
| Cell Wall | composed of cellulose; provides structural support for a plant |
| Vacuole | large structure that stores water and the materials dissolved in it; associated with plant cells |
| Nuclear Membrane | determines what enters and leaves the nucleus |
| Chromatin | DNA and proteins that when coiled forms chromosomes |
| Nucleolus | structure within the nucleus that produces ribosomes |
| Cilia | short, hairlike structures that help with cell movement |
| Flagella | whiplike structure associated with cell movement; sperm cells have this |
