5 Kingdoms of Living Organisms

5 Kingdoms of Living Organisms

• Kingdom Monera: Single-celled organisms without a nucleus (prokaryotes), including bacteria and blue-green algae.
• Kingdom Protista: Mostly single-celled eukaryotic organisms with a nucleus, including algae, protozoa, and slime molds.
• Kingdom Fungi: Multicellular, eukaryotic organisms that cannot produce their own food (heterotrophic), including mushrooms, molds, and yeasts.
• Kingdom Plantae: Multicellular, eukaryotic organisms that can produce their own food through photosynthesis (autotrophic), including trees, flowers, and ferns.
• Kingdom Animalia: Multicellular, eukaryotic organisms that cannot produce their own food (heterotrophic), and are motile, including mammals, birds, reptiles, amphibians, fish, and insects.

Seven Level Classification System

• Domain: The highest level of classification that categorizes organisms based on their fundamental cellular structure.
• Kingdom: Categorization of organisms based on broad similarities in their general characteristics, cell structure, and mode of nutrition.
• Phylum: Groups organisms within a kingdom based on their shared body plan and organization.
• Class: Groups organisms within a phylum based on shared structural and functional characteristics.
• Order: Groups organisms within a class based on similar traits like their reproductive systems and behavior.
• Family: Groups similar organisms within an order based on shared characteristics in their morphology, reproductive systems, and physiology.
• Genus: Groups closely related organisms within a family based on their shared evolutionary lineage and specific characteristics.
• Species: The most specific level of classification, grouping organisms that can interbreed and produce fertile offspring.

Diversity of Animals

• Characteristics: Multicellular, eukaryotic, heterotrophic, motile, with specialized tissues and organs for various functions.
• Classes:
  • Mammals: Warm-blooded with fur or hair, give birth to live young, and nurse their offspring with mammary glands.
  • Birds: Warm-blooded with feathers, lay eggs, and have wings for flight.
  • Reptiles: Cold-blooded with scales, lay eggs, and have a three-chambered heart.
  • Amphibians: Cold-blooded with smooth, moist skin, lay eggs in water, and undergo metamorphosis.
  • Fish: Cold-blooded with fins, gills for breathing underwater, and lay eggs.
  • Insects: Cold-blooded with exoskeletons, six legs, and usually wings.

Diversity of Plants

• Characteristics: Multicellular, eukaryotic, autotrophic, non-motile, with cell walls made of cellulose and different reproductive mechanisms.
• Types:
  • Bryophytes: Non-vascular plants like mosses and liverworts, lacking specialized vascular tissue for transporting water and nutrients.
  • Pteridophytes: Vascular plants including ferns, horsetails, and clubmosses, that use spores for reproduction.
  • Gymnosperms: Vascular plants including conifers like pines and spruces, that have seeds but do not produce flowers.
  • Angiosperms: Vascular plants that produce flowers and enclosed seeds within fruits.
