Study Notes

Branches of Biology

  • Taxonomy: Focuses on the identification, nomenclature, and classification of plants and animals.
  • Ecology: Primarily considers interactions between organisms and their environment, including the study of ecosystems.
  • Morphology: Concentrates on the form and structure of organisms, including their physical characteristics.

Inheritance and Reproduction

  • Genetics: Involves the study of inheritance and how different characteristics are passed from parents to offspring.

Types of Asexual Reproduction

  • Asexual Reproduction: Generates offspring from a single parent without the involvement of gametes.
  • Binary Fission: A common method of asexual reproduction where a single cell divides into two daughter cells, prevalent in microorganisms like bacteria.
  • Gemmulation: A reproductive process in sponges that involves the formation of internal buds known as gemmules.
  • Bud Formation: A form of asexual reproduction where a new organism develops from an outgrowth or bud from the parent organism.

Sexual Reproduction Processes

  • Conjugation: Process where two similar organisms fuse, exchange genetic material, and then separate, typically observed in algae.
  • Pollination: The transfer of pollen from the male part (anther) of a plant to the female part (stigma) to facilitate fertilization.
