Match the following columns and select the correct choice:
| Column I | Column II | ||
|---|---|---|---|
| A | Autogamy | I | Transfer of pollen to a different plant bringing genetic variation |
| B | Geitonogamy | II | Invariably observed in cleistogamous flowers |
| C | Xenogamy | III | Functionally cross-pollination, genetically autogamous |
| D | Cleistogamy | IV | Pollination within the same flower |
Correct answer · Option 1
A-IV, B-III, C-I, D-II
Explanation
Step-by-step matching for types of pollination:
1. Autogamy (A) is the transfer of pollen grains from the anther to the stigma of the same flower (IV).
2. Geitonogamy (B) is functionally a cross-pollination involving a pollinating agent, but genetically it is similar to autogamy since the pollen comes from the same plant (III).
3. Xenogamy (C) involves the transfer of pollen grains from anther to the stigma of a different plant of the same species, which brings about genetic variation (I).
4. Cleistogamy (D) refers to flowers that do not open at all; autogamy is invariably observed in such cleistogamous flowers (II).
Therefore, the correct matching is A-IV, B-III, C-I, D-II.
