Document Summary
Lectures #1- 9 with lab/lit; january 4th, 2015. Locate the eyespot on an image of chlamydomonas: eyespot (red spot in chloroplast, but unrelated to chloroplast functions)= light sensor that processes info as to the location and intensity of a light source. Characteristics of chlamydomonas that make it a useful model system: diploid and haploid; sexual and asexual, single-celled photosynthetic eukaryote, diverged early in evolutionary history -> shares similarities with different taxa, light for both information (eyespot) and energy (chloroplast) Relatedness of chlamydomonas to plants and animals: diverged on linneage leading to plants (not classified as plant -> considered protist, more closely related to plants than animals. Relationship between genome size and protein coding genes: bigger genome size more protein coding genes or compexity. Humans have 3000mb but only 20 000 pcg; chlamy: 120mb & 15 000 from light source -> move using flagella. Distinctions between primitive, complex, simple: primitive= old, complex= bigger genome, simple= smaller genome.
