Criteria for Autogamy to Take Place

Q.

Protoandry and protogyny are examples of

1. Dichogamy

2. Heterostyly

3. Herkogamy

4. Cross pollination

Q.

The one advantage of cleistogamy is :

1. It leads to greater genetic diversity

2. Seed dispersal is more efficient and widespread

3. Seed set is not dependent on pollinators
4. Each visit of pollinator results in the transfer of hundreds of pollen grains

Q. Pollinators are not required for successful pollination and fertilisation when the flowers exhibit

1. chasmogamy
2. herkogamy
3. dichogamy
4. cleistogamy
