Amoeba vs. Paramecium: Know the Difference
By Shumaila Saeed || Published on January 9, 2024
Amoeba is a shapeless, unicellular organism moving via pseudopodia, while Paramecium is a slipper-shaped, unicellular organism using cilia for movement.
Key Differences
Amoeba possesses a flexible shape, constantly changing due to the formation of pseudopodia (false feet) for movement and feeding. Paramecium, in contrast, has a fixed, slipper-like shape with a rigid structure and moves using numerous tiny hair-like structures called cilia.

Amoeba typically thrives in freshwater environments, soil, and in some parasitic forms, inside host organisms. Paramecium is mainly found in freshwater environments, where its cilia not only aid in movement but also in creating currents to channel food particles towards its oral groove.

The Amoeba engulfs food particles through a process called phagocytosis, where it extends its pseudopodia around the food to enclose it in a food vacuole. Paramecium feeds by sweeping food particles into its oral groove using cilia, where they are then engulfed into food vacuoles.

Amoeba generally reproduces asexually through binary fission, where the cell divides into two daughter cells. Paramecium also reproduces primarily asexually by binary fission, but it can engage in a form of sexual reproduction known as conjugation for genetic variation.

Amoebas play a key role in the decomposition process and nutrient cycling in their environments. Paramecia, being a part of the aquatic food chain, serve as food for larger organisms and aid in controlling algae populations.
