Reproduction in Organisms

• Reproduction is a characteristic feature of all organisms for the continuation of species
• Modes of reproduction – Asexual and sexual, Asexual reproduction
• Modes- Binary fission, sporulation, budding, gemmule, fragmentation; vegetative propagation in plants

Sexual Reproduction in Flowering Plants
