Document Summary
Relatedness of chlamydomonas to plants and animals: genome sequence of chlamy has attributes of plants and animals (prokaryotic and eukaryotic genes, distantly related to plants, and more distantly related to animals. Advantages to working with haploid chlamy: only one mating type in the flask, purely asexual reproduction, when flask is in light, lots of nutrients available and the cells divide (as seen on the left) 3: part of eyespot is in chloroplast and part of it is in plasma membrane. In summary: light is absorbed, changes flow of ions, causes depolarization of the membrane, shoots down cell to membrane, eye spot and flagella are therefore linked through this action potential. Advantages to chlamydomonas in being phototactic: chlammy uses eyespot to undergo phototaxis. Phototaxis: ability of chalmy to move towards or away from light. 4: light transport or taxi, chlamydomonas moves towards light to harness energy of photons in photosynthesis and absorb more light, too much light makes too much p680+
