Document Summary
Heterotrophs- obtain their organic material from other organisms chloroplasts in mesophyll cells- chloroplasts are found in here, each stomata (pores)- co2 and o2 enter and exit the leaf through microscopic pore. Autotrophs- sustain themselves without eating anything from other organisms= Photosynthesis- the process that converts solar energy into chemical energy (basically food), directly or indirectly, photosynthesis nourishes almost the entire living world plants, algae, some protists, some prokaryotes- these actually do photosynthesis. Leaves- chloroplasts- the site of photosynthesis in plants (stomata), the cytoplasm of chloroplast mesophyll cell contains 30-40 chloroplasts. Chloroplasts likely evolved from bacteria (like mitochondria), green color is from chlorophyll membranes of thlakoids; thylakoids may be stacked in columns called grana. Chloroplasts also contain stroma, a dense interior fluid. Intro to the light reactions and the calvin cycle (light reactions and the dark reactions) part), split h2o, release o2, reduce nadp+ to nadph (p means extra phosphate), generate atp from adp by photophosphorylation.
