Yes indeed. 3.31 a) is an example of ciliates, which usually has a constant body shape, generally asymmetrical, although some have acquired radial or bilateral symmetry. In addition, they have a mouth in their cell and using their cilia, they sweep up the food along with some water into their cell mouth, and then transfer into the oral groove. Uploaded By LUKEHUGH87. They have a moveable membrane called a pellicle which is actually a cell membrane and not a cell wall as exists in plants.
