Cells vocabulary
| Term | Definition |
|---|---|
| prokaryotic cells | no true nucleus, No membrane-bound structures and always unicellular examples: bacteria |
| Eukaryotic Cell: | Has a true nucleus - Has membrane-bound organelles - Some unicellular, most MULTICELLULAR Examples: Animals, Plants, and Fungi |
| are cells an open system? | YES |
| what is a closed system? | only energy can go in and out |
| what is an open system? | system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components |
| what is an isolating system? | nothing goes in or out |
| cell membrane | a double layer of lipids and proteins that surrounds a cell. provides protection for a cell. both |
| nucleus | organelle that contains genetic material (DNA) of eukaryotic organisms. like brain of cell both |
| chloroplasm | creates glucose through photosynthesis in plants only. plants |
| vacuoles and vesicles | Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. both |
| endoplasmic reticulum (ER) | The endoplasmic reticulum is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum. function is to produce proteins for the rest of the cell to function both |
| ribosomes | produce protein - found on the rough ER or free in the cytoplasm both |
| cytoplasm | gel like substance inside cell membrane that supports and protcts organells both |
| cell wall | A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. plants. |
| lysosomes | They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. like stomach of cell. animal only. |
| golgi apparatus (golgi body) | packages, labels and inspects protein from ER to be transported too rest of cell or out of cell. like post office of cell. both. |
| mitochondria | bean shaped organell. power house of the cell. both |
| cilia | helps in cell movement and feeling animals only |
| flagella | tail like projections. cells on,y have one or two. mostly see bacterial cells. heps with movement. animals only |
| what is ATP? | energy |
