Document Summary
Uses light in two di erent ways (chloroplasts use light as a source of energy and uses light through the eyespot to sense its environment/information) Genome: the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism. The complete set of genes or genetic material present in a cell or organism. Chlamydomonas has three genomes (nuclear genome, chloroplast genome, mitochondrial genome) Synechocystis is a bacterium which is photosynthetic even though it is a prokaryotic cell. An open reading frame (orf) is a sequence of dna that is predicted (through a computer algorithm) to encode a protein predicted protein coding gene. Easy to grow (liquid media in small asks, streaked on agar plates) Phototaxis: positive and negative phototaxis (controlled by eyespot) Chlamydomonas has agella which can propel it towards (positive) or away from (negative) a light source.
