Vedclass · Answer

(B) $1$. Statement $A$ is true: For autogamy (self-pollination) to occur,the anther and stigma must be in close proximity.$2$. Statement $B$ is false: The plants $Viola$,$Oxalis$,and $Commelina$ produce two types of flowers: chasmogamous and cleistogamous. Cleistogamous flowers do not open at all,ensuring self-pollination. The option incorrectly lists $Zostera$ instead of $Oxalis$ or $Commelina$ and generalizes the entire plant as cleistogamous.$3$. Statement $C$ is true: Dioecious plants (e.g.,papaya) have separate male and female plants,so geitonogamy (transfer of pollen from anther to stigma of another flower on the same plant) cannot occur.$4$. Statement $D$ is true: Geitonogamy involves pollen transfer between flowers of the same plant,meaning the genetic makeup of the pollen and the ovule is identical,similar to autogamy.
