| Aspect | Amoebae | Zooflagellates |
| Cell type | Unicellular, usually with a simple cell structure. | Unicellular, typically with a more defined and organized cell structure. |
| Movement | Locomotion is usually achieved by cytoplasmic streaming and the formation of pseudopodia (false feet). | Locomotion is typically facilitated by one or more flagella. |
| Feeding Mechanism | Phagocytosis | May use a combination of phagocytosis, absorption, or symbiotic relationships for obtaining nutrients. |
| Habitat | Found in freshwater and marine habitats, as well as in soil. | Found in diverse environments, including aquatic habitats, soil and as symbionts in the digestive tracts of some animals. |
| Types of reproduction | · Binary fission · Multiple fission · Some amoebae can also undergo sexual reproduction | · Binary fission · Multiple fission · Sexual reproduction |
| Flagella | Lack flagella | Possess one or more flagella |
| Diseases | · Amoebic dysentery | · African sleeping sickness · Giardiasis |
| Cell Structure | Typically lack a rigid cell wall, allowing flexibility in shape. | May have a more defined cell structure, often with a pellicle or other structural features. |
| Ecological Role | Play roles as predators in microbial food webs, contributing to nutrient cycling. | Some are important members of microbial communities, participating in nutrient cycling. Others may cause diseases in their hosts. |
| Examples | · Amoeba proteus · Entamoeba histolytica | · Trypanosoma · Giardia · Trichomonas |
