Reproduction Reproduction in organisms: reproduction, a characteristic feature of all organisms for continuation of species; asexual reproduction modes of reproduction - asexual and sexual reproduction;modes-binaryfission,sporulation,budding,gemmule,fragmentation;vegetative propagationinplants. Sexual reproduction in flowering plant: flower structure; development of male and female gametophytes;pollination-types,agenciesandexamples;outbreedingdevices;pollen-pistil interaction; double fertilization; post fertilization events - development of endosperm and
