Question

Circle the odd one out. Give reasons for your choice.

nitrogen, chlorophyll, carbon dioxide, sunlight, water.

Answer 1

Nitrogen is the odd one out.

Reason - Nitrogen does not take part in the process of photosynthesis.

Photosynthesis- The process by which plants use carbon dioxide and water in presence of sunlight to form sugar (carbohydrate) and oxygen.

$\mathrm{Carbon}\mathrm{dioxide}\left(\mathrm{g}\right)+\mathrm{Water}\left(\mathrm{l}\right)\stackrel{\mathrm{sunlight}}{\to }\mathrm{Glucose}\left(\mathrm{s}\right)+\mathrm{Oxygen}\left(\mathrm{g}\right)$
