Study Notes
Taxonomy and Classification
- Properties of tissues arise from the interactions among the molecular components comprising the organelle
- Number of species known and described range between 1.7-1.8 million
- Agreed principles and criteria for plants are provided by ICBN (International Code of Botanical Nomenclature)
- Animals are named by ICZN (International Commission of Zoological Nomenclature)
- Founder of Taxonomy is Aristotle
- Carolus Linnaeus gave the concept of Binomial Nomenclature
- Biological names are generally in Latin and written in italics
- Specific epithet starts with a small letter
Taxonomic Categories
- The taxonomic groups are distinct biological entities and not merely morphological aggregates
- Taxonomic categories from highest to lowest: Kingdom, Phylum, Class, Order, Family, Genus, Species
- Solanum genus includes species like Nigrum, melongena, and tuberosum
- Panthera includes species like Leo, tigris, and pardus
- Family Solanaceae contains genera like Solanum, Petunia, and Datura
- Felidae contains genus Panthera and Felis
Taxonomic Aids
- Herbarium is a storehouse of collected plant specimens that are dried, pressed, and preserved on sheets
- Herbarium serves as a quick referral system in taxonomic studies
- Herbarium sheets carry a label providing information about date and place of collection, English, local, and botanical names, family, collector's name, and other details
- Museums have collections of preserved specimens, including skeletons of animals
The Living World
- Ernst Mayr is known as the "Darwin of the 20th century"
- Increase in mass and number are twin characteristics of growth
- Growth and reproduction are mutually exclusive in some organisms
- Living organisms grow intrinsically
- Reproduction is a defining property of living organisms
- Metabolism is the sum total of all chemical reactions occurring in the body
- Cellular organization is a defining feature of living organisms
- Consciousness is a defining feature of living organisms
Defining Features of Living Organisms
- Metabolism
- Consciousness
- Cellular organization
Biological Species
- Ernst Mayr is known for defining biological species
- A biological species is a group of organisms that can interbreed and produce fertile offspring
