Document Summary

Characteristics of chlamydomonas that make it a useful model system. Branched off early in the lineage the eventually lead to plants. Not on the branch that lead to animals/humans and fungi. Relationship between genome size and protein coding genes complexity. Genome size (the number of genes in an organism) generally isnt a good indicator of. The genome size and the amount of protein coding genes can show the amount of dna. The larger the genome size there is a high possibility of pcg, but it doesn"t necessarily mean that larger genomes will have more pcg. When light hits channel rhodopsin it acts like a pore which opens up allowing calcium ions and protons to flow through. This causes a depolarization of the plasma membrane and an action potential which travels down to the flagella causing it to move in being phototactic. Its need light to produce energy from photosynthesis. Chlamydomonas might move away from a light source.
