| Question | Answer |
|---|---|
| cell | basic unit of living things |
| prokaryote | organism that lacks membrane bound organelles |
| eukaryote | organism that has membrane bound organelles |
| organelle | specialized structure that carries out a specific cell function |
| nucleus | control center of the cell |
| plasma membrane | phospholipid bilayer that surround all cells, it controls what enters and leave the cell |
| cytoplasm | jel-like material that surround all the organelles inside the plasma membrane and outside the nuclear membrane |
| phospholipid bilayer | two layers of phospholipids that are arranged tail to tail creating a hydrophobic region in the middle with the hydrophillic phosphate heads facing the water |
| fluid mosaic model | liquid like example of a membrane in which the solid phospholipid molecules act more like a fluid with other molecules floating in it. |
| cell wall | outermost cell layer of bacteria, fungi and plants. Gives those cells their characteristic structure and shape |
| mitochondria | location where cellular respiration takes place providing energy for the cell |
| chloroplast | photosynthetic organelle that changes light energy into chemical energy all cells can use |
| golgi apparatus | packages the materials made by the ER for export from the cell |
| endoplasmic reticulum | folded membrane system that provides quick transportation in the cell as well as a place for ribosomes to attach |
| lysosome | vacuole containing digestive enzymes |
| ribosome | small organelle that makes protein |
| nucleolus | organelle that is located in the nucleus that produces ribosomes |
| vacuole | storage container in the cell, plants have one really big one that contains water, animals have several small ones |
| cilia | tiny hairlike projections that beat like oars on a viking ship to move the cell |
