What feature do mosquito pupae possess to assist with breathing?

• A. Gills
• B. Respiratory tubes
• C. Air sacs
• D. Tracheae

Answer: (B)

Mosquito pupae are unique among insects in the way they breathe, utilizing specialized structures known as respiratory tubes. These tubes extend from the surface of the pupae into the air, allowing for efficient gas exchange. The respiratory tubes are adapted to enable the pupae to obtain oxygen from the atmosphere while remaining partially submerged in water. This anatomical feature is critical for their survival during the pupal stage, where they undergo significant development before emerging as adult mosquitoes. Other options, although related to respiratory functions in insects and aquatic life, do not accurately describe the specific adaptation found in mosquito pupae. Gills are typical in aquatic organisms like fish for extracting oxygen from water, while air sacs and tracheae relate more to other insect respiratory systems but do not represent the characteristic feature of mosquito pupae. Thus, the presence of respiratory tubes is a vital adaptation that supports respiration in these organisms during their pupal stage.
