1. Paramecium

2. Characteristics Called ‘Ciliates’ – from cilia Single-celled organisms Found in fresh water, some in salt and brackish water all over the world. Have cilia – help with movement and feeding Heterotrophic

3. Structure (Macronucleus) pellicle

4. Cilia Pellicle Macronucleus Micronucleus Contractile vacuole Oral groove/ mouth pore Gullet Food vacuole Trichocyst Ectoplasm Endoplasm Anal pore 2. Thick outer membrane – Gives it shape 3. Controls the cell’s activities 4. Can have many of these; contain the chromosomes and are used only during conjugation. 5. Remove excess water out of the cell; works like a pump. 6. Takes in food here 8. Food is digested 9. Get rid of undigested food particles here 10. Protection or defense against predators

5. Reproduction Asexually through binary fission

6. Sexually through conjugation 2 Paramecium connect at the oral grooves and exchange micronuclei
