Question 5

Self pollination is a form of:&#10;A)Inbreeding&#10;B)Out breeding&#10;C)Random mating&#10;D)None of these

Accepted Answer

Self-pollination is a form of inbreeding because it involves the fertilization of a flower by pollen from the same plant, leading to genetic similarities between parent and offspring.

Question 6

Cross pollination is associated with:&#10;A)Cleistogamy&#10;B)Chasmogamy&#10;C)Dichogamy&#10;D)Apogamy

Accepted Answer

Cross-pollination is associated with chasmogamy, which refers to flowers that are open and accessible to pollinators.

Question 7

Completion of pollination and fertilization in unopened flower bud is termed as&#10;A)Chasmogamy&#10;B)Apogamy&#10;C)Cleistogamy&#10;D)Dichogamy

Accepted Answer

Cleistogamy refers to a form of pollination that occurs within an unopened floral bud, ensuring self-fertilization. This contrasts with chasmogamy, where flowers open and might undergo cross-pollination.

Question 8

Maturation of anthers and stigma at the same time refers to:&#10;A)Homogamy&#10;B)Chasmogamy&#10;C)Cleistogamy&#10;D)Dichogamy

Accepted Answer

Homogamy refers to the maturation of anthers and stigma at the same time, facilitating self-pollination.

Question 9

Fertilization after opining of flower refers to:&#10;A)Cleistogamy&#10;B)Chasmogamy&#10;C)Homogamy&#10;D)Herkogamy

Accepted Answer

Chasmogamy refers to the fertilization that occurs after the flower has opened, allowing for the exposure of the reproductive parts to potential pollinators.
