🌍 What is Diversity in Living Things?

Our planet Earth is home to millions of different types of living organisms! From tiny bacteria to giant whales, from colorful flowers to towering trees - life exists in countless forms. This amazing variety is called biodiversity.

Why do we need to classify living things?

  • • To study and understand them better
  • • To identify relationships between organisms
  • • To organize scientific knowledge
  • • To communicate about organisms clearly

🌿 Kingdom Plantae

🌳
  • Characteristics: Make their own food (photosynthesis)
  • • Have cell walls made of cellulose
  • • Cannot move from place to place
  • Examples: Trees, flowers, grass, ferns
  • Types: Flowering plants, non-flowering plants

🐅 Kingdom Animalia

🦁
  • Characteristics: Cannot make their own food
  • • Can move freely
  • • Have specialized organs
  • Examples: Mammals, birds, fish, insects
  • Groups: Vertebrates & Invertebrates

🍄 Kingdom Fungi

🍄
  • Characteristics: Cannot make their own food
  • • Absorb nutrients from dead matter
  • • Have cell walls made of chitin
  • Examples: Mushrooms, yeast, molds
  • Role: Decomposers in nature

🦠 Kingdom Protista

🦠
  • Characteristics: Single-celled organisms
  • • Have a nucleus (eukaryotic)
  • • Live in water environments
  • Examples: Amoeba, Paramecium, Euglena
  • Types: Plant-like, animal-like, fungus-like

🦠 Kingdom Monera

🧬
  • Characteristics: Single-celled organisms
  • • No nucleus (prokaryotic)
  • • Very simple structure
  • Examples: Bacteria, Blue-green algae
  • Importance: Helpful and harmful bacteria

🔬 Classification Hierarchy

📊
  • Kingdom (largest group)
  • Phylum/Division
  • Class
  • Order
  • Family
  • Genus
  • Species (smallest group)

🔑 Key Concepts to Remember

🧬 Binomial Nomenclature

Every organism has a scientific name with two parts: Genus + Species (e.g., Homo sapiens for humans)

🌱 Autotrophs vs Heterotrophs

Autotrophs make their own food (plants), Heterotrophs depend on others for food (animals)

🔬 Prokaryotes vs Eukaryotes

Prokaryotes have no nucleus (bacteria), Eukaryotes have a nucleus (plants, animals)

🌍 Biodiversity Importance

Variety of life maintains ecological balance and provides resources for humans
