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. Web11 de abr. de 2024 · I worked on Tetrahymena ODAs, which are what power the beating of cilia, right at the beginning of my postdoc; I spent 6 months purifying and trying to crystalize them.
