Document Summary

Heterotrophic animals: take complex organic molecules and break them down into smaller molecules, use energy released, can"t fix carbon, use reduced organic molecules like fats, glucose, proteins. Autotrophic plants: take an inorganic form of carbon and fixes it into a complex organic form. Chemoautotrophs use chemical energy to perform this process, photoautotrophs use light from the sun: add energy to molecule (uses sun to perform task) Has mouth and digestive system, has eyes, sensory organs. No chloroplasts when young, feeds on algae: brown colour. Merges chloroplasts into cells, digests rest of plant: turns green. Chloroplast is a plastid (has 4 membranes when in alga, only 2 when isolated) Process of stealing chloroplasts from plants and incorporating it into the new body. Isolate chloroplasts: degrade because it has no protein sources. Proteins breakdown after a while and need to be replaced. Measuring photosynthesis: measure amount of o2 released, or consumption of co2.
