Document Summary
You will get more gold from this lecture if you come prepared by looking over: i) Section 1. 1 in biology: exploring the diversity of life, 2nd ed. 1. 1. (what you should be able to do after attending and reviewing the lecture. Characteristics of chlamydomonas that make it a useful model system. Chlamy is a sexually acive, light-harvesing, carbon-reducing, hydrogen-belching planimal. Has a single, very large chloroplast containing thylakoid membranes. Dna in the nucleus and in the chloroplasts (prokaryoic and eukaryoic genes in the same cell) 10 micrometers across (prokaryotes are usually 1 micron and eukaryotes are usually 10x larger) Model system for photosynthesis, eukaryoic cell structure and funcion. Divides every 8 hoursasexually but if you mix male and female they can undergo lifecycle> Light as an energy source --> making atp/energy (like plants it is photosyntheic. Trap and use light to acquire informaion about surroundings! Has lagella like eukaryotes but also has chloroplasts --> diverged from plants.
