Study Notes

Reproduction in Living Organisms

Sexual reproduction involves the union of two gametes from different individuals, resulting in offspring with a mix of characteristics from both parents.
Asexual reproduction encompasses binary fission, budding, spore production, and vegetative reproduction through various methods such as runners, suckers, cutting, and tubers.
Binary fission occurs in single-celled organisms like bacteria, amoeba, and algae, where a cell divides into two identical cells.
Budding involves the production of a smaller version of the parent, which can break off or remain attached as a self-sufficient individual, seen in organisms like Hydra, yeast, and coral.
Spores are similar to seeds but with only one set of DNA, and are produced by fungi, green algae, molds, and ferns.
Vegetative reproduction methods include runners, suckers, and tubers, seen in plants like strawberries, cherry trees, and potatoes.
Sexual reproduction involves the exchange of genetic material between two individuals, resulting in genetically different offspring.
In animals, sexual reproduction involves the union of male gametes (sperm cells) and female gametes (egg cells) through fertilization, leading to the formation of a zygote, which develops into an embryo.
Twins have been used in scientific studies to understand the roles of genetics and environment in human traits and diseases.
In plants, sexual reproduction involves pollen, stamen, ovules, and pistil, leading to the production of embryos in the form of seeds.
Cross-pollination and cross-fertilization occur in plant sexual reproduction, leading to the formation of zygotes.
Seed dispersion methods include wind, animal, and self-propelled mechanisms, aiding in reducing competition between parent and new plants.
