Answers
a) 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
b) 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
c)) light reaction takes place in grana of chloroplast and light independent reaction takes place in stroma .
light reaction utilizes light energy whereas dark reaction may occur in presence of light but does not utilize light .
light reaction end products are ATP,NADPH whereas light independent reaction produces glucose
d)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.
