kingdoms of life cognito

    Cards (32)

    • What are the five kingdoms of life excluding viruses?
      Animals, plants, fungi, protists, and bacteria
    • Why are viruses considered the odd one out among living organisms?
      Because they are not classified as living organisms
    • What type of cells are animals, plants, fungi, and protists made up of?
      Eukaryotic cells
    • What is a key characteristic of eukaryotic cells?
      They have DNA in the form of chromosomes located in a nucleus
    • How do bacteria differ from eukaryotic organisms?
      Bacteria are prokaryotic and do not have a nucleus
    • How much smaller are bacteria compared to eukaryotic cells?
      Bacteria are between 10 and 100 times smaller than eukaryotic cells
    • What is the estimated number of animal species on Earth?
      Between 5 and 10 million species
    • What are the three main characteristics of animals?
      They are multicellular, heterotrophs, and most reproduce sexually
    • What does it mean for an organism to be multicellular?
      It means that the organism is made up of many cells
    • How do animals obtain their energy?
      Animals are heterotrophs and obtain energy from other organisms
    • How many species of plants are estimated to exist?
      Around 300,000 species
    • What distinguishes plants from animals in terms of energy acquisition?
      Plants are autotrophs and obtain energy through photosynthesis
    • What is the difference between unicellular and multicellular fungi?
      Some fungi are unicellular like yeast, while others are multicellular like mushrooms
    • How do fungi obtain their energy?
      Fungi are heterotrophs and obtain energy from other organisms
    • What is saprotrophic nutrition in fungi?
      It is a process where fungi secrete enzymes to digest food outside their body
    • What is mycelium in fungi?
      Mycelium is a body made up of thread-like structures called hyphae
    • What are pathogens in the context of fungi?
      Pathogens are fungi that can cause disease in humans
    • What do the terms protists, protista, and protester refer to?
      They all refer to the same kingdom of organisms
    • What is a key characteristic of most protists?

      Most protists are unicellular organisms
    • How do some protists obtain energy?
      Some protists have chloroplasts and can photosynthesize, while others consume other organisms
    • What is an example of a protist that causes disease?
      Plasmodium, which causes malaria
    • What are bacteria classified as?
      Single-celled organisms
    • Where can bacteria be found?
      Bacteria can be found almost everywhere, including on skin and in intestines
    • How do most bacteria obtain their energy?
      Most bacteria feed off other organisms, either living or dead
    • What is a common disease caused by bacteria?
      Salmonella, which causes food poisoning
    • How do viruses differ from other organisms?
      Viruses are not considered living organisms and are classified as particles
    • What is the basic structure of a virus?
      A virus has a protein coat surrounding genetic material, which can be DNA or RNA
    • How do viruses reproduce?
      Viruses can only reproduce inside living cells by infecting other organisms
    • Why are viruses considered parasites?
      Because they depend on other organisms to grow and reproduce
    • What is a common example of a virus that causes disease?
      Influenza virus, which causes influenza
    • What are the key differences between the five kingdoms of life?
      • Animals: multicellular, heterotrophs, reproduce sexually
      • Plants: multicellular, autotrophs, use photosynthesis
      • Fungi: can be unicellular or multicellular, heterotrophs, use saprotrophic nutrition
      • Protists: mostly unicellular, diverse energy acquisition methods
      • Bacteria: single-celled, diverse habitats, some can photosynthesize
    • What are the main characteristics of viruses?
      • Not considered living organisms
      • Composed of a protein coat and genetic material (DNA or RNA)
      • Can only reproduce inside living cells
      • Considered parasites as they depend on hosts to replicate
