Photosynthesis
Chapter 8 Zlatan Horozovic 2R 1) Trace electrons through the pathways of photosynthesis from their excitation by photons to the production of sugar. In photosynthesis the electron transport pathway is an integral part of the light reactions. Light that we see and plants use for photosynthesis is a small part of the spectrum of electromagnetic radiation, from just below 400 nm to just above 700 nm. ... Because of that C4 plants very effectively optimize photosynthesis under conditions that make photosynthesis of C3 plants not very possible. ... These plants must maintain high rates of photosynthesis and growth even though their stomata closes at times so it can limit water loss. ... Both mesophyll layers carry on photosynthesis but the bundle sheath cells do not.
