Question: Which among the following components is NOT a necessary component for photosynthesis?
Options:
Carbon dioxide
Water
Sunlight
Nitrogen
-Nitrogen is not a necessary component for photosynthesis.
🔑Key Points:
-Photosynthesis is a process by which food is prepared by plant cells.
✏️The components involved in the photosynthesis process are:
-Chlorophyll:
-It is the green colored pigment present in plant cells.
-Cells present in leaf take part in photosynthesis as they possess chlorophyll.
-Organelles grana and stroma in chlorophyll is where photosynthetic reaction takes place.
✏️Carbon dioxide:
-During photosynthesis, the carbon dioxide is converted into glucose through various reactions.
-Plant cells acquire the cabon dioxide from open atmosphere.
✏️Water:
-Water is necessary for the photosynthetic light reaction.
-Roots of the plants absorb water by osmotic process.
-The absorbed water reaches the photosynthetic cells of the leaves through vascular xylem tissues.
✏️Sunlight:
-Photosynthesis only complete when visible light is absorbed by chlorophyll.
-Thus sunlight is necessary for photosynthesis.
-Photosynthetic reaction is maximum in red colored light and minimum for violet colored light.
