WebTetrahymena exposed to various concentrations of Congo Red. The results of their research revealed a positive, linear relationship between time and mean number of Congo Red vacuoles (4). In our lab, we fed the Tetrahymena India ink rather than Congo Red or Carmine Red, primarily due to practical reasons; the red colored particles were more WebThe membranelle acts as a collecting sieve, where the food particles become trapped in the free spaces between the cilia. Using this mode of feeding, ciliates can shift considerable volumes of water in relation to their size. Tetrahymena, for example, can filter 3,000 to 30,000 times its own volume in one hour.
