Given below are two statements : Statement I: Cleistogamous flowers...
Given below are two statements :
Statement I: Cleistogamous flowers are invariably autogamous
Statement II: Cleistogamy is disadvantageous as there is no chance for cross pollination
In the light of the above statements, choose the correct answer from the options given below :
Options
- ABoth Statement I and Statement II are incorrect
- BStatement I is correct but Statement II is incorrect
- CStatement I is incorrect but Statement II is correct
- DBoth Statement I and Statement II are correct
Correct answer
D. Both Statement I and Statement II are correct
Step-by-step solution
Cleistogamous flowers mean anther and stigma present close each other in the closed flower. They are bisexual which cannot open even at maturity and thus self-pollination occurs. For this reason these type of flowers are invariably autogamous. Cleistogamous flowers undergo self-pollination only, which reduces the chances of variation and evolution of genetically superior progeny.
