CHAPTER 7 How do Organisms Reproduce? Mechanisms by which organisms reproduce? Organisms reproduce to ensure the continuation of their species. The mechanisms of reproduction can be broadly categorized into asexual reproduction and sexual reproduction: 1. Asexual Reproduction Involves a single parent, and offspring are genetically identical to the parent (clones). Mechanisms: Binary Fission: Organism splits into two identical cells (e.g., bacteria, amoeba). Budding: A small bud grows on the parent and detaches to form a new organism (e.g., yeast, hydra). Fragmentation: Parent breaks into fragments, each developing into a new organism (e.g., starfish, spirogyra). Spore Formation: Spores are produced and dispersed to grow into new individuals (e.g., fungi, mosses). Vegetative Propagation: New plants grow from parts like roots, stems, or leaves (e.g., potatoes, bryophyllum). Sexual Reproduction Involves two parents, and offspring inherit genetic materia...
