Description
Lecture 1 1. Chlamydomonas:  Sexually active  Light-harvesting  Carbon-reducing  Hydrogen-belching Planimal Organelle type Function Nucleus Contains the cell's DNA (genetic information) in the form of genes Rough Endoplasmic Consists of many interconnected membranous sacs called cisternae, onto whose Reticulum (RER) external surface ribosomes are attached. Ribosomes - Produce polypeptides Smooth Endoplasmic Consists of many interconnected membranous sacs called cisternae (without Reticulum (SER) ribosomes). Golgi Apparatus The Golgi apparatus modifies, sorts and packages macromolecules for delivery to other organelles or secretion from the cell via exocytosis Mitochondria production of energy by synthesis of ATP Chloroplasts Chloroplasts are the sites of photosynthesis within plant cells. Flagella To move Pyrenoid centers of carbon dioxide fixation within the chloroplasts Eyespot a photoreceptive organelle. Outer membrane of chloroplast. Can swim has flagella. Move to light region to get Energy. 2. Evolution of Complexity  Latin, complexus: 2 or more of simpler stuff come together and get more complex  Genome has nothing to do with complexity  PCG (Protein Coding Gene
