Cells
| Question | Answer |
|---|---|
| 1. Cells | The basic units of structure and function in living things. |
| 2. Organelles | “Organs” of a cell. They are groups of complex molecules that help cells survive |
| 3. Examples of organelles | Cell membrane, cell wall, cytoplasm, vacuole, mitochondria, endoplasmic reticulum, nucleus and chloroplast. |
| 4. Cell Membrane | It acts as a bondary layer around the cytoplasm thus separating cells from their outside enviroments. |
| 5. Cell Wall | It provides protection from physical injury and provides structural support. |
| 6. Cytoplasm | Is a suspension fluid that houses the other organelles. |
| 7. Vacuole | This stores water and ingested food in a fluid sack. |
| 8. Mitochondria | They take in nutrients, break them down and create energy for the cell. |
| 9. Endoplasmic Reticulum | Transports chemicals between and within cells. |
| 10. Nucleus | The "brain" of the cell. It contains chromosomal information on chromatin. |
| 11. Chloroplasts | Are the food producers in a plant cell. |
| 12. Plant Cell consist of.. | Chloroplast, Cell wall, Big vacoule, Mitochondria, Goglie Apparatus, Nucleus, Endoplasmic Reticulum, Ribosomes, and Cell Membrane. |
| 13. Animal Cell consist of.. | Mitochondria, Golgi Apparatus, Nucleus, Endoplasmic Reticulum, Ribosomes, Cell Membrane, and Lysosome. Sometimes there are small vacoules. |
| 14. Cell Organization | Multicellular organisms are made up of differentiated cells that are organized in specific ways to perform specialized functions. |
| 15. Tissue | Interconnected cells |
| 16. Organ | Is a group of tissues that work together to perform a specifice function. |
| 17. Organ System | Composed of organs with interrelated functions. |
| 18. Levels of Organization | Cells -> Tissues -> Organs -> Organ Systems |
| 19. Difference between the plant and animal cell.. | The plant cell has a big vacoule, chloroplast and a cell wall. The animal cell have lysosomes. |
| 20. Who has cells? | Every living thing. |
| 21. Golgi Apparatus | Waste disposal and also processes, sorts, and modifies proteins in cells. |
| 22. Ribosomes | They are RNA and protein complexes that are found in all cells |
| 23. Chromatin | Composed of long, thin strands of DNA which contains “instructions” that control cell metabolism and heredity. |
| 24. Lysosomes | Contain enzymes specialized to break down ingested materials, secretions, and wastes. |
