| Question | Answer |
| B1.1 Cell structures | Plant cells -contain the same as an animal cell but also CELL WALLS, CHLOROPLASTS and VACUOLE |
| Animal cells -found in animals and humans. -contain a NUCLEUS, CYTOPLASM, CELL MEMBRANE, RIBOSOMES AND MITOCHONDRIA. | Microscopes -helps the specimens cells, tissues and other structures to be viewed . Makes them appear in detail and larger. - |
| Calculate magnification Magnification of eye piece X magnification of objective lense. E.g. eye piece=10. Objective= 4. 10 X 4= 40 | Calculating size of an image Size of image= real size of object X magnification CAN BE REARRANGED. |
| Eukaryotic cells are animal and plant cells. Prokaryotic cells are bacteria. Bacteria cells. don’t have a nucleus PRO MENAS BEFORE NUCLEUS | -Prokaryotic cells have A CELL WALL, CELL MEMBRANE, CYTOPLASM, PLASMID and a SINGLE LOOP OF DNA. - they also have ribosomes but do not have a nucleus. |
| Differences between the two -Eurkaryotic cells divide through mitosis. Prokaryotic divide through Binary fission. -Eukaryotic cells have DNA in the nucleus but prokaryotic only have a single loop. |
