Protozoa (Ciliata) {ciliate}| can have cilia. Paramecia have oval shape, 2500 cilia, and two contractile vacuoles.
sensation
Paramecia have bilateral receptors, have neurofibril between basal bodies, and can sense if stimulus is from front or rear.
reproduction
Paramecia have one micronucleus for reproduction and one macronucleus for metabolism. Paramecia have eight mating types.
movement
Paramecia swim by spiraling forward. Touch, heat, cold, chemicals, and light change cilia beating and so swimming direction and speed, separately on each side. Paramecia cilia on both sides can go forward or reverse, or one side can go forward while other side does nothing.
