Document Summary
1st law cannot be created or destroyed. 2nd law convert between types kinetic, chemical, potential. Photosynthesis process by which plants and algae convert sunlight to chemical energy. Autotrophs(producers) self feeders (plant, algae, some bacteria) Heterotrophs (consumers) obtain energy bu eating other organisms. Sunlight + water + co2 o2 + glucose. Chemical energy used to make glucose molecules using the carbon atoms of co2. The removal of co2 from the atmosphere helps to attenuate the effects of climate change. Deforestation becoming a huge issue due to this. Photosynthesis reactions occur inside plant cell organelles called chloroplasts. Chloroplast 2 membranes and thylakoid membrane; own dna and ribosomes. Light energy is electromagnetic radiation and has particles called photons. Blue/violet and red/orange can be absorbed by plants. 500 650 (yellow and green) cannot be absorbed by plants. Whatever color you see, that wavelength is being reflected. In the fall, chlorophyll is more dormant and other pigments become most prominent.
