The Science of Existence (93-3) Paramecia


Paramecia have 2 sets of selfsame cilia. One puts a move on, while the other facilitates feeding, by sweeping nutrients into oral grooves.

Paramecia locomotion cilia are powered by a different motor than feeder cilia. Viscosity slows paramecia motion, but feeding cilia are unaffected. Getting around is less important than chowing down.
