A) \[C{{O}_{2}}\] is released without any absorption of \[{{O}_{2}}\]
B) \[{{O}_{2}}\] is absorbed but \[C{{O}_{2}}\] is not released
C) There is often compensation point in these plants due to thick phylloclades
D) None of these
Correct Answer: B
Solution :
[b] In succulent plants like Opuntia, there is an incomplete oxidation of the carbohydrates resulting in the formation of organic acids. \[C{{O}_{2}}\] is not released. \[2{{C}_{6}}{{H}_{12}}{{O}_{6}}+3{{O}_{2}}\to 3{{C}_{4}}{{H}_{6}}{{O}_{5}}+3{{H}_{2}}O+386\,\,kcal.\]\[R.Q.=\frac{C{{O}_{2}}}{{{O}_{2}}}=\frac{O}{3}=O\]You need to login to perform this action.
