|---|---|
 prokaryote | a cell without a nucleus |
| bacteria | this is an example of a prokaryote |
| eukaryote | a cell with a nucleus |
| plant and animal cell | 2 examples of eukaryotic cells |
| cell, tissue, organ, organ system | list the levels of cellular organization in order from smallest to largest |
| cell membrane | regulates what enters and leaves the cell |
| cell membrane | made up of a phospholipid bilayer |
| cell wall | found in plant cells only and it is located outside of the cell membrane |
| chloroplasts | organelle found in plant cells only its function is to trap light energy from the sun and convert it to chemical energy during photosynthesis |
| cytoplasm | jelly-like material made of water, NaCl, and organic material; it is constantly in motion and it contains organelles |
| smooth endoplasmic reticulum | organelle that consists of an interconnected membrane network of folded sacs and tunnel; no ribosomes; contains a collection of enzymes to make membrane lipids and detoxification of drugs ribosomes are found on the surface of this organelle |
| rough endoplasmic reticulum | ribosomes are found on the surface of this organelle |
| mitochondria | this organelle carries out cellular respiration (energy center of the cell) |
| nucleus | this is the information center of the cell or the "brains" of the cell; it directs all cell activities |
| nucleus | this part of the cell contain hereditary information (DNA) |
| ribosomes | organelle that is the site of protein synthesis |
| lysosome | small organelle that is used for clean up and waste management |
| lysosome | small organelle that contains enzymes that digest food particles, broken cell parts, and bacteria that are trapped by white blood cells |
| golgi body | organelle that modifies, sorts and packages proteins and other materials from the endoplasmic reticulum |
| cytoskeleton | this shapes and supports the cell and is involved in movement; it is made up of microtubules and microfilaments |
| cytoskeleton | this is made up of microtubules and microfilaments |
| vacuole | stores water, salts, proteins, and carbohydrates and creates internal pressure in plants |
| nucleolus | site where ribosomes are synthesized (made) and assembled |
| flagella | whip like structures made up of microtubules; they are used for movement |
| cilia | short, hair like structures that are used for movement |
| Make sure you know | how to label both the plant and animal cells organelles and the difference between a plant and an animal cell. |
