Document Summary
Characteris. cs of chlamydomonas that make it a useful model system. Chlamydomonas is a unicellular eukaryote with haploid gene:cs possessing both agella and chloroplast. Relatedness of chlamydomonas to plants and animals. One of which is the classic eukaryo:c agella, the same ones human cells have that allows cells to move around. Rela. onship between genome size and protein coding genes. This indicates that there is no real rela:onship between genome size and pcgs. Phototransduc. on from eyespot to agella. This process also occurs in chlamydomonas from the eyespot to the agella opera:ng with a high degree of similarity. Advantages to chlamydomonas in being phototac. c. Phtotaxis is essen:ally light transport, the ability to move towards/away from the light. This allows chlamydomonas to orient themselves most e ciently to receive light for photosynthesis. Dis. nc. ons between primi. ve, complex, simple. Amoebas and bacteria may seem simple compared to trees or elephants but in reality there is no way to tell.
