Green Algae Genome Gives History Lesson (2 of 7)

Caption: Electron micrograph of the apical end of a Chlamydomonas cell showing the two flagella, their transitional regions, and their basal bodies, which are connected by striated fibers. The cluster of vesicles beneath the basal bodies represent the contractile vacuole. Portions of the cup-shaped chloroplast (one of which contains a starch granule) are visible on either side of the contractile vacuole. This image relates to an article that appeared in the Oct. 12, 2007, issue of the journal Science, published by AAAS. The study, by Dr. Sabeeha S. Merchant and colleagues at the University of California, Los Angeles in Los Angeles, was titled "The Chlamydomonas Genome Reveals the Evolution of Key Animal and Plant Functions."
