Webformation of T. thermophila can be applied to all the functions of cilia which collectively are essential for its survival. In addition, observations in this study could have implications for human ciliated cells. Clary-Meinesz et al. (1992) found that as temperature increased, ciliary movement increased in the human nasal and tracheal cells until about 20°C, after which it 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.

WebCilia are made up of microtubules coated by the plasma membrane. Each cilium comprises nine pairs of microtubules that form the outside ring and two central microtubules. This structure is called an axoneme. The nine outer pairs are made up of motor proteins called dynein. These are large and flexible that allows the cilia to move.
