A plant is provided with ideal conditions for photosynthesis and supplied with isotope 14 CO ₂ . When the products of the process are analysed carefully, what would be the nature of products?

Options

  1. AGlucose and oxygen are labelled
  2. BOxygen is labelled, but glucose is normal
  3. CGlucose and oxygen are normal
  4. DGlucose is labelled, but oxygen is normal

Correct answer

D. Glucose is labelled, but oxygen is normal

Step-by-step solution

In the process of photosynthesis 6 CO ₂+12 H ₂ O [ Chl ] hv aligned & C ₆ H ₁₂ O ₆+6 H ₂ O +6 O ₂ & (Glucose) aligned Plants manufacture glucose from H ₂ O and CO ₂ and oxygen gas is released. So, due to isotopic carbon of CO ₂ , only glucose will be labelled, but oxygen will be normal.
