BIOL 3200 Lecture Notes - Lecture 14: Electron Transport Chain, Photosystem Ii, Light-Independent Reactions
Document Summary
Freshwater, marine, soil, rocks o o: mostly unicellular (cocci, bacilli, spirilli) o. Can be filamentous (multicellular) long chains of cells that can have a sheath around them. Sheath coding to cover the entire set up o o. Can move in a gliding motion as a whole unit. Produce a lot of their own food: what develops into chloroplasts in plants (endosymbiosis) They can convert nitrogen gas to ammonia o. Can help soil to be richer and more productive for other plants. Trichomes ! multicellular assoications: with sheath, without sheath. Rounder cells are filled with gases (hetercysts ! flotation devices) they suspend organisms in the water and keep them. At a level that is optimal for photosynthesis. Away from ultraviolent light (protection against thymine dymers) Use water to get electrons to reduce power. High number of mesosomes (folds: more mesosomes, more photosynthesis will occur o. Ongoing energy production, will not produce as much energy though.
