|2.||Pollination by water is quite rare in flowering plants|
|3.||Pollination by wind is more common amongst abiotic pollination|
|4.||Flowers produce foul odours to attract flies and beetles to get pollinated|
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:
1. I is incorrect but II is correct.
2. Both I and II are correct.
3. Both I and II are incorrect.
4. I is correct but II is incorrect.
