The letter "A" represents the nucleus of the flame cell, which plays a role in regulating the fluid balance in planarians. The flame cell is responsible for collecting excess water and waste in the body and excreting it out of the organism. The cilia create a current that moves the fluid towards the flame cell, where it is processed and eliminated.
