Key Difference: Both these words come under the same microorganisms and have the same characteristics: Bacteria and Parasite. Both of these microorganisms will help in improving ecosystems and are harmful too. Bacteria are prokaryotic whereas protozoa are eukaryotic microorganisms. Bacteria have flagella to move and protozoa are less movement than bacteria. Bacteria adapt in all environments, whereas protozoa mostly live in aquatic ecosystems. You can learn the significant differences between bacteria and protozoa in this article.
Good Examples of the words “Bacteria and Protozoa” are,
1. Bacteria do not have a nucleus.
2. Protozoa are generally motile in nature.
BACTERIA
Bacteria are prokaryotic organisms.
Bacteria are microscopic, single-celled organisms with no nucleus and no organelles. Some bacteria are harmful and produce toxins; toxic chemicals affect them, and some are harmless. It is a prokaryotic and single cell’s organism. Humans have long used bacteria to create food products such as cheese, yoghurt, and pickles. Most of the bacteria are fast-growing and are first called animalcules.
There are two types of bacteria, one is Gram-positive, and the other one is Gram-negative. The major difference in both types is gram-negative bacteria have an outer membrane in their body. The world’s first bacteria are cyanobacteria. Bacteria are the smallest living organism on this planet. The main characteristic of bacteria is it doesn’t have membrane-bound organelles in its body. The Best Example of Bacteria is “Bacteria lives in pH neutral.”

PROTOZOA
Protozoa is a unicellular microorganisms.
Protozoa is a diverse group of single-celled microorganisms that are found in aquatic and terrestrial environments. It plays an important part in the microbial ecosystem and plays roles in ecological processes such as predation and parasitism. It involves both beneficial and harmful, which is important in medical research and for studying cellular processes and disease mechanisms. The Best example of the word “Protozoa” is “There are different 1000 species in protozoa.”
