Cards in this deck (5)
- 1B1.1 Cell structuresPlant cells
-contain the same as an animal cell but also CELL WALLS, CHLOROPLASTS and VACUOLE - 2Animal 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.
- - 3Calculate magnification Magnification of eye piece X magnification of objective lense. E.g. eye piece=10. Objective= 4. 10 X 4= 40Calculating size of an image
Size of image= real size of object X magnification
CAN BE REARRANGED. - 4Eukaryotic 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. - 5Differences 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.
