Cells and Microscope
| Question | Answer |
|---|---|
| What characteristics do living things share? | reproduce, grow and develop, need energy, respond to stimuli (move), have cells |
| What is an organism? | any living thing |
| Organelle | small parts of a cell |
| Cell | smallest part of livinv things |
| Prokaryotic Cell | example is bacteria. Cell that does NOT have a membrane around its nucleus |
| Eukaryotic cell | plants and animals. Cells that HAVE membranes around their nucleus |
| Cell membrane | lets things in/out of the cell |
| Cell wall | in a plant cell only; offers protection and support for the plant cell |
| Nucleus | the "boss" of the cell that directs the activities of the cell |
| chromosomes or DNA | genetic material that make us who we are; found in the nucleus |
| Cytoplasm | gel-like fluid in the cell |
| chloroplast | organelle that uses sun's energy in a plant cell only to create food |
| Vacuole | in both plants and animals but much larger in the plant; stores water, nutrients and waste |
| Endoplasmic Reticulum (ER) | transportation channels in the cell |
| Golgi Bodies | packages, arranges, organizes things to go outside of the cell |
| What is the difference between smooth and rough ER? | Rough ER has ribosomes on it |
| What 2 places in the cell are ribosomes found? | in the cytoplasm floating around and on the rough ER |
| What is chlorophyll? | the green chemical, or pigment, that makes leaves green. Exists in the chloroplasts of plant cells |
| Nucleolus | center pit of the cell |
| What do plant cells have that animal cells do not? | cell wall, chloroplast, and larger vacuoles |
| How does a cell's shape match its function | Lots of cells are shaped for their job. Red blood cells look like fun innertubes, nerve cells have long tendrils coming off them, plant cells are rigid |
| Mitochondria | powerhouse of the cell; converts food and other materials into energy for the cell's processes |
| What 3 parts do all cells have? | nucleus, cell membrane, and cytoplasm |
