Match the following types of pollination / floral conditions with their correct description: Column I (Types) 1. Autogamy 2. Geitonogamy 3. Xenogamy 4. Cleistogamy 5. Chasmogamy Column II (Description) A. Flowers remain closed; ensures obligate self-pollination without external agents B. Pollen transfer within the same flower; requires synchrony of anther and stigma C. Cross-pollination between two genetically different plants D. Flowers open; expose anthers and stigma, permitting self or cross-pollination E. Pollen transfer from one flower to another flower of the same plant
View solution & NCERT explanation
Correct answer: B — 1-B, 2-E, 3-C, 4-D, 5-A
Autogamy → B: Pollination occurs within the same flower (self-pollination) Geitonogamy → E: Pollen transfer occurs between different flowers of the same plant. Xenogamy → C: Pollen transfer occurs between flowers of different plants of the same species, ensuring genetic variability. Cleistogamy → D: Cleistogamous flowers never open and thus always undergo self-pollination. Chasmogamy → A: Chasmogamous flowers open at maturity, exposing reproductive parts, allowing either self or cross-pollination.
