Which of the following terms is related to self-pollination?

Show Answers

Spatial separation of reproductive organs (Herkogamy)Temporal separation of male and female phases (Dichogamy)Pollination involving open flowers (Chasmogamy)Pollination within the same flower without separation (Homogamy)

Self-pollination occurs when pollen from the same flower fertilizes its ovules, a process known as homogamy. In contrast, herkogamy refers to spatial separation of reproductive parts, dichogamy involves timing differences in maturation, and chasmogamy describes pollination in open flowers.
