| cell | basic unit of structure and funcion in all living things |
| eukaryotic cells | cells that contain nucleus and other structures that surrounded by a cell membrane |
| prokaryotic cells | cell that do not have a nucleus or membrane bound organelles |
| nucleus | a large strudcture inside a cell that contains genetic material and controls the cell's activitiews |
| chromatin | a grandular materail spread throughout the nucleus that is made up of DNA |
| chromosomes | threadlike structures that is made up of condensed chromatin |
| nucleolus | a dense region inside the nucleus where ribosomes are assembled |
| ribosomes | are small structure made up of RNA and proteins-- a they make proteins |
| cell membrane | a thin flexible barrier that surrounds the cell |
| cell wall | a rigid barier surrounding plant cells made up of cellulose which prevents plants from moving |
| cytoplasm | the liquid located inside a cell between the cell membrane and the nucleus |
| organelles | tiny structures located in the cytoplasm |
| endoplasmic reticulum | is an organelle that makes parts of the cell membrane and chemically change some proteins |
| rough endoplasmic reticulum | endoplasmic reticulum that have ribosomes attache to it |
| smooth endoplasmic reticulum | endoplasmic reticulum that doesnt have ribosomes attache to it |
| golgi vesicles | attaches carboydrates and lipids to proteins |
| lysosomes | break down food particles that are taken into the cell and organelles that are not longer needed by the cell |
| mitrochondria | organelles responsible for releasing energy from stored food molecules to power all cell functions |
| celluar respiration | the process by which mitochondria break down sugar (glucose) into carbond dioxide and water releasing energy |
| chloroplast | found in plants that contain a green pigment chlorophyll that gives plant their green color are used to make food for a plant cell--they are not found in an animal cell |
| vacuole | a large organelle that is found in plants that stores water and other dissolved minerals |
