Marina Voloshina Phys-Math School, Novosibirsk State University, 2008 http://www.slideshare.net/outdoors Cell objects size and number the Cell Inside 3. 1 millimeter (mm) 5 0 average animal cells Cells are very small 4. 20 μ m ( micro meters) 1 micro meter = 10 –6 meter Average human cell 7. real cell our × 1 000 000 1 micrometer 1 meter 1 nanometer 1 millimeter 9. The walls – cell membrane are very thin. 1 cm only 1 cm 12. 5 cm pore 5 cm envelope Chromosomes inside chromosome 20 cm thick 14. Chromosomes are made of DNA – the information storage molecule The cell brain 2 mm 50 kilometers unfolded DNA of one chromosome 15. In cell division the nucleus brakes down and chromosomes go out A-A-A ! 18. Back to non-dividing cell A-A-A ! 23. Better to think of mitochondria as a fireplace It produces energy ATP ATP 24. Bacterial cells are the same size as mitochondria Infection ! Bacteria not allowed 26. But very important No cell can exist without them Ribosomes make proteins – the “working horses” of cell 27. If ribosome would be 2 cm then an average protein – just 0.5 29. Ribosomes produce proteins – and cytoplasm is crowded with them Cytoplasm: thick like porridge 34. Lysosomes are for digestion Digestive enzymes Digestive system 35. Man has bones and muscles Cell has a cytoskeleton made of protein fibers and tubules 42. Chloroplasts for photosynthesis 5 meters 10 – 100 chloroplasts per a plant cell 43. Photosynthesis Sun light CO 2 from the air All plants and animals exist due to Sun energy fixed in this amazing process Organic matter 44. You can barely move in plant cell. Most of space is occupied with giant central vacuole Central vacuole
