Definition of the noun Imaginal disc

What does Imaginal disc mean as a name of something?


  1. [biology] Any of several pairs of discs within the body of a larva that become part of the outside during pupal transformation


Imaginal disc: An imaginal disc is one of the parts of a holometabolous insect larva that will become a portion of the outside of the adult insect during the pupal transformation. Contained within the body of the larva, there are pairs of discs that will form, for instance, the wings or legs or antennae or other structures in the adult. The role of the imaginal disc in insect development was first elucidated by Jan Swammerdam.
