MCQ ON PHOTOSYNTHESIS IN HIGHER PLANTS
MCQ PHOTOSYNTHESIS IN HIGHER PLANTS is useful for NEET / CSIR / UGC / CBSE / ICSE / AIIMS / EXAM / AFMC EXAM / STATE LEVEL MEDICAL EXAM 2022-23
Introduction:-
All animals including human beings depend on plants for their food. Green plants carry out photosynthesis a physico – chemical process by which they use light energy to drive the synthesis of organic compounds. Ultimately , all living forms on earth depend on sunlight for energy.The use of energy from sunlight by plants doing photosynthesis is basis of life on earth. The use of energy from sunlight by plants doing photosynthesis is the basis of life on earth. Photosynthesis is important due to two reasons : it is the primary source of all food on earth.It is also responsible for the release of oxygen into the atmosphere by green plants.
