Document Summary
3 domains: bacteria, archaea, eukarya share one common ancestor. Key difference animal and plant: plants have chloroplast, cell wall, central vacuole, osmotic pressure for movement, animals have nervous, muscloskeletal system, muscle pump for transport. Plant perception is usually on a cellular/subcellular level, animals use complex organs. Hormones in both plants and animals, but only animals have neural system for faster info transport. Photosynth: 6co2 + 12h2o + light c6h12o6 + 6o2 + 6h2o. Light dependant: 2h20 + light 4h + 4e + o2. Light independent: co2 + 4h + 4e ch2o + h2o. Respiration: c6h12o6 + 6o2 6co2 + 6h2o + atp + heat. Light dependant split water to extract e, which are excited to produce nadh + atp, reducing power then used to reduce co2 to carbohydrate. Main photosynthetic pigments: carotenoids absorb blue and green, chlorophylls absorb red and blue. Excited electrons can: fluoresce heat and light, resonance transfer transfer energy (but not e) between adjacent pigments in antenna.
