Study Notes
Structure of Paramecium
- Small hair-like growths called cilia emerge from the surface of the entire body
- A central granule called the motor granule (Motorium) is present near the cellular pharynx, to which all motor bodies are attached
Locomotion
- Paramecium moves using its cilia, with movement occurring in successive waves on the animal's surface
Nutrition and Digestion
- The parts of the body absorb digested materials from food vacuoles
- At the end of food vacuole movements, they explode at a temporary opening called a temporary anus (cytoproct)
Reproduction
- Two mated individuals exchange male nuclei through a protoplasmic bridge
- In each individual, one nucleus increases in size to form a large female nucleus (stable), while the other remains small
