Study Notes

Classification of Living Organisms

  • Living organisms are classified based on similarities and differences in characteristics.
  • Organisms are grouped into separate categories according to shared traits.
  • Classification helps to understand the relationships between organisms.

Five Kingdom System

  • Organisms are organized into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
  • These kingdoms are differentiated based on their structural, functional, and other features.

Monera

  • Single-celled organisms.
  • Includes bacteria.
  • Some bacteria can produce their own food.
  • Some cause diseases.

Protista

  • Mostly single-celled organisms.
  • Includes amoeba, paramecium, and algae.
  • Some have chlorophyll for photosynthesis.

Fungi

  • Some are single-celled.
  • Many have filament-like structures.
  • Cannot produce their own food.
  • They absorb nutrients from their surroundings.
  • Examples include yeast, molds, and mushrooms.

Plantae

  • Multicellular organisms.
  • Contain chlorophyll for photosynthesis.
  • Make their own food.
  • Examples include flowering plants and ferns.

Animalia

  • Multicellular organisms.
  • Cannot produce their own food.
  • They obtain nutrients by consuming other organisms.
  • Examples include mammals, birds, reptiles, amphibians, fish, and invertebrates.

Classification of Vertebrates

  • Vertebrates have a backbone and internal skeleton.
  • They include fish, amphibians, reptiles, birds, and mammals.
  • Each group has specific characteristics.

Classification of Invertebrates

  • Invertebrates do not have backbones.
  • Major groups include sponges, worms, insects, mollusks, and echinoderms.
  • Unique characteristics for each group.

Biodiversity

  • Biodiversity is the variety of life in a particular area.
  • Extinct organisms are no longer found.
  • Endangered organisms are at risk of extinction.
  • Important to conserve biodiversity.
  • Human activities can negatively impact biodiversity (e.g., deforestation, excessive hunting).
  • There are conservation measures for endangered species (e.g., game reserves, national parks).
