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 nature of products

Options

A. Giucose and oxygen are labelled
B. Oxygen is labelled, but glucose is normal
C. Glucose and oxygen are normal
D. Glucose is labelled, but oxygen is normal

Answer

D

Explanation

In the process of photosynthesis
`6CO_(2)+12H_(2)Ounderset(Chl)overset(hv)tounderset(`(Glucose)`)(C_(6)H_(12)O_(6))+6H_(2)O+6O_(2)uarr`
Plants manufacture glucose from `H_(2)O` and `CO_(2)` and oxygen gas is released, So, due to isotopic catbon of `CO_(2)` only glucose will be labeiled, but oxygen will be normal.
