Difficulty: EasyGaseous Exchange and Cellular Respiration

Match each organism in Column I with its corresponding structure used for gaseous exchange in Column II.

  • AmoebaCell membrane
  • Tilapia (Fish)Filamentous gills
  • Grasshopper (Insect)Tracheoles
  • Flowering plantStomata

Answer

Amoeba pairs with Cell membrane, Tilapia pairs with Filamentous gills, Grasshopper pairs with Tracheoles, and Flowering plant pairs with Stomata.
Each organism is correctly paired with its evolutionary adaptation for gas exchange: Amoeba uses its cell membrane, Tilapia uses filamentous gills, Grasshoppers use tracheoles, and flowering plants use stomata.

Step-by-Step Solution

1
Determine the gaseous exchange surface for single-celled protozoans such as Amoeba.
Amoeba matches with Cell membrane.
Due to its high surface area-to-volume ratio, Amoeba does not require specialized respiratory organs and relies on direct diffusion across the cell membrane.
2
Determine the organ adapted for aquatic respiration in bony fish like Tilapia.
Tilapia matches with Filamentous gills.
Water passes over the gill filaments where oxygen diffuses into blood capillaries while carbon dioxide diffuses out.
3
Identify the respiratory structures in terrestrial insects like the Grasshopper.
Grasshopper matches with Tracheoles.
Insects transport gases directly to tissue cells via a system of chitinous tubes that divide into fine tracheoles.
4
Identify the primary structure for gas exchange in angiosperm leaves.
Flowering plant matches with Stomata.
Stomata are specialized leaf pores bounded by guard cells that open and close to facilitate carbon dioxide uptake and oxygen release.

Key Concept

Adaptive diversity of specialized respiratory surfaces across unicellular, multicellular animal, and plant groups.
