PHOTOSYNTHESIS - Coggle Diagram
PHOTOSYNTHESIS
Biosphere is a region on the earth and atmosphere where living organisms exist and they are driven by photosynthetic power of green plants
-
Light is a type of electromagnetic radiation and travel as waves or photons ( shorter wave length have more energy

Chloroplast is an organelle in plants and algae that carries out photosynthesis and the green pigment is called chlorophyll
Energy cycle- cells use organic molecules for energy and plants replenish molecules through photosynthesis and o2 is produced
Trophic levels are: heterotroph must eat food - Autotroph makes organic molecules from inorganic molecules - Phototroph uses light energy as source such as green plants and algae and cyanobacteria
Light reaction- uses light energy and takes place in thylakoid membrane and produces o2 and NaDH and ATP

Absorption Spectrum- Wavelenght that are absorbed by different pigments/ Action spectrum- photosynthesis rate at a specific wavelenght
When an electron absorbs energy it becomes at an exited state and unstable and release energy as light or heat
Exited electrons travel from PSII to PSI- Energy is released in ETC- Oxizides water to form H+ and o2
PSI- primary role is to form NADPH adding H+ to NADP contributes to the H+ gradient by depleting H+ From stroma
