Asked by | 03 Jun, 2009, 09:02: PM
Expert Answer
Cleistogamous flowers do not open whereas chasmogamous flowers open.
Cleistogamous flowers can only carry out self-pollination whereas chasmogamous flowers are usually cross-pollinated (and sometimes self-pollinated)
In cleistogamous flowers, reproductive structures are often smaller and less pollen needs to be produced as compared to chasmogamous flowers. Cleistogamous flowers are non-showy and inconspicuous whereas chasmogamous flowers are showy and highly conspicuous. Cleistogamous flowers are homogamous whereas chasmogamous flowers are usually dichogamous. Cleistogamous flowers do not need any agents for pollination whereas chasmogamous flowers are dependent on pollination agents since they arre usually cross-pollinated.
