Two different types of heterostyly are seen in such bisexual flowers: These are found in Jasmine and Primrose (. },{ Homogamy or the maturation of male and female reproductive organs at the same time. The ovules of flowering plants are stored in a hollow body called the pistil, and pollen is deposited on the stigmas surface. Autogamy is achieved by the following methods: In homogamy, stamens and stigma of a flower mature at the same time and are brought closer by growth, bending, or folding. Each stamen has a short filament and a long curved connective with two unequal arms. It occurs only in gymnosperms and angiosperms. Since most blooming plants can't fertilise all alone, they need to depend on different creatures.
