Study Notes

Living Being Characteristics

  • Consciousness is the ability to respond to stimuli and sense the environment, with humans being self-conscious.
  • All organisms are composed of cells, with body organization starting from sub-microscopic molecular levels.
  • Growth is characterized by an increase in mass and number, but it's not a defining feature of living beings.
  • Reproduction occurs through two ways: sexual and asexual, ensuring the continuity of species.
  • Metabolism involves catabolism and anabolism, and is a defining feature of living beings, with cellular metabolism occurring at all times.

Taxonomy

  • Systematic is a branch of science that deals with the diversity of organisms and their relationships, encompassing characterization, identification, classification, and nomenclature.
  • Classification is done by analyzing similarities and dissimilarities among organisms.
  • Binomial nomenclature is a system of naming organisms, with plants named by ICBN and animals by ICZN, developed by Carolus Linnaeus.
  • A binomial name consists of a generic name starting with capital letters, and a specific epithet starting with small letters, often written in italics or underlined.
  • An author's name may be added to the biological name.

Important Books

  • Systems Naturae and Genera Plantarum are books written by Carolus Linnaeus.

Botanical Garden, Zoological Park, and Herbaria

  • Botanical gardens are places where living plants are labelled with their biological names, such as the Indian Botanical Garden in Howrah, famous for the Great Banyan Tree.
  • Zoological parks, or zoos, are dedicated to protecting wild animals in their natural environment.
  • Herbaria are repositories for dried plant specimens, along with information like date and place of collection, and the name of the collector.

Taxonomical Aid

  • A key is a taxonomical aid based on similarities and dissimilarities, used for identification, with each statement leading to a pair of contrasting characters, or couplet.

Miscellaneous

  • Flora refers to the distribution of plants in a region.
  • Manuals provide information for identifying species in a region.
  • Monographs contain collective data on a single taxon.
  • Catalogues have brief information about species found in a region.

Museum and Taxonomical Categories

  • Museums are repositories for plant and animal specimens, often established in educational institutions.
  • A taxon is the unit of biological classification, sometimes confused with categories, such as a division being a category, and Bryophyta being a taxon.
  • Taxonomical hierarchy, in order of increasing number of common characters, consists of: Kingdom, Phylum, Class, Order, Family, Genus, and Species, with Kingdom being the most inclusive and Species being the least inclusive.
