    • What is osmoregulation?
      Maintaining water and salt concentration
    • Osmoregulation is only necessary for freshwater animals
      False
    • Freshwater fish drink large amounts of water to osmoregulate
      False
    • What happens if cells become too concentrated or too dilute?
      They become damaged
    • Match the osmotic challenge with the correct animal:
      Excess water influx ↔️ Freshwater animals
      Water loss ↔️ Saltwater animals
    • Which excretory organs are involved in osmoregulation?
      Kidneys, skin, lungs, liver
    • Osmoregulation maintains a constant water and salt concentration for proper cell function

      True
    • Osmoregulation is crucial because it maintains a constant internal water and salt concentration
    • Compare the osmoregulation strategies of freshwater and saltwater fish
      1️⃣ Water intake in freshwater fish: through gills and food
      2️⃣ Water intake in saltwater fish: drinking water
      3️⃣ Urine in freshwater fish: large volume, dilute
      4️⃣ Urine in saltwater fish: small volume, concentrated
    • Freshwater and saltwater animals face different osmotic challenges
    • What do saltwater animals drink to maintain osmoregulation?
      Seawater
    • The kidneys regulate the volume and composition of urine
    • Osmoconformers adjust their internal osmotic pressure to match the environment

      True
    • Osmoregulators actively control their internal osmotic pressure
    • Saltwater fish excrete small volumes of concentrated
    • Why is osmoregulation important for cell function?
      Maintains water and salt balance
    • Freshwater fish excrete large volumes of dilute
    • Saltwater animals excrete excess water through concentrated urine
      True
    • Freshwater fish excrete large volumes of dilute urine
    • Match the excretory organ with its function:
      Kidneys ↔️ Produce urine, regulate water balance
      Skin ↔️ Excretes water and salts through sweat
      Lungs ↔️ Remove carbon dioxide and water vapor
    • How do freshwater fish obtain water?
      Through gills and food
    • What happens if cells become too concentrated or too dilute?
      They become damaged
    • Freshwater fish actively take in salts and excrete excess water
      True
    • What is the osmotic challenge faced by freshwater animals?
      Excess water influx
    • Match the excretory organ with its function in osmoregulation:
      Kidneys ↔️ Filter blood to produce urine
      Skin ↔️ Excrete excess water and salts
      Lungs ↔️ Remove carbon dioxide and water vapor
      Liver ↔️ Metabolize waste products
    • What are the two main categories of organisms based on osmoregulation?
      Osmoconformers and osmoregulators
    • What is an example of an osmoconformer?
      Jellyfish
    • Match the species with its osmoregulation mechanism:
      Freshwater Fish ↔️ Excrete dilute urine, absorb salts
      Saltwater Fish ↔️ Drink water, excrete salts
      Mammals ↔️ Regulate urine production, sweat glands
