Which one of the following may require pollinators, but is genetically similar to autogamy?
1. | Geitonogamy | 2. | Xenogamy |
3. | Apogamy | 4. | Cleistogamy |
Which of the following are the important floral rewards to animal pollinators?
Geitonogamy involves:
1. | Pollination of a flower by the pollen from another flower of the same plant. |
2. | Pollination of a flower by the pollen from another same flower. |
3. | Pollination of a flower by the pollen from a flower of another plant in the same population. |
4. | Pollination of a flower by the pollen from a flower of another plant belonging to a distant population. |
Advantage of cleistogamy is:
1. More vigorous offspring
2. No dependence of pollinator
3. Vivipary
4. Higher genetic variability
1. | Cleistogamous flowers are always autogamous |
2. | Xenogamy occurs only by wind pollination |
3. | Chasmogamous flowers do not open at all |
4. | Geitonogamy involves the pollen and stigma of flowers of different plants |
Both, autogamy and geitonogamy are prevented in:
1. Papaya
2. Cucumber
3. Castor
4. Maize
Even in the absence of pollinating agents, seed-setting is assured in:
1. Commelina
2. Zostera
3. Salvia
4. Fig
Plants with ovaries having only one or a few ovules are generally pollinated by:
1. Butterflies
2. Birds
3. Wind
4. Bees
