MCQ ON RESPIRATION IN PLANTS class 11 for NEET
MCQ RESPIRATION IN PLANTS is useful for NEET / CSIR / UGC / CBSE / ICSE / AIIMS / EXAM / AFMC EXAM / STATE LEVEL MEDICAL EXAM 2022-23
Introduction:-
All of us breathe to live , but why is breathing so essential to life ? What happens when we breathe ? Also , do all living organisms , including plants and microbes , breathe ? If so, how ?
All living organisms need energy for carrying out daily life activities , be it absorption , transport , movement , reproduction or even breathing . Where does all this energy come from ? We know we eat food for energy but how is this energy taken from food ? How is this energy utilised ? Do all foods give the same amount of energy ? Do plants eat ? Where do plants get their energy from ? And micro- organisms – for their energy requirements , do they eat food.
