1. Asexual Reproduction
- Binary Fission: A single organism divides into two equal halves, each becoming a new individual. Common in unicellular organisms like Amoeba and Paramecium.
- Multiple Fission: The nucleus divides multiple times before the cell splits into several daughter cells. Observed in organisms like Plasmodium.
- Budding: A new organism develops from an outgrowth or bud due to cell division at one particular site. Seen in Hydra and Yeast.
- Fragmentation: The body of the parent breaks into distinct pieces, each of which can develop into a new individual. Common in algae like Spirogyra.
- Vegetative Propagation: New plants grow from vegetative parts like roots, stems, and leaves. Examples include Bryophyllum and Potato.
2. Sexual Reproduction
- Gametogenesis: The process of formation of male and female gametes. Involves meiosis, leading to genetic variation.
- Fertilization: The fusion of male and female gametes to form a zygote. Can be internal or external, depending on the species.
- Post-fertilization Events: Includes zygote development, embryogenesis, and formation of new individuals.
