Light reaction takes place in grana of chloroplast and light independent reaction takes place in stroma .
light reaction utilises light energy whereas dark reaction may occur in presence of light but does not utilize light .
light reaction endproducts are ATP,NADPH whreas light independent reaction produces glucose
chloroplast is membrane bound structure and is a cell organelle which is center for light and light independent reactions whereas chlorophyll is a pigment essentially required for photosynthetic reactions like light and dark reaction.
auto trophic nutrition is a type of nutrition in which organisms derive nutrients by preparing their own food materials ex:photosynthetic bacteria and green plants.
hetero tropic nutrition : organism depend on several food sources ex:parasitic plants,animals
Nutrition: the procurement of nutrients
Ingestion :taking of food by mouth
digestion :breakdown of large or complex food materials into simple substances so that cell can absorb and assimilate it
