the difference between bacteria and protoctist is that the protoctist have a necleus while the bacteria don't.... in other words the bacteria is a prokaryotes and the protoctist is a eukaryotes
Unicellular protoctists are eukaryotic organisms that can be photosynthetic, heterotrophic, or mixotrophic in nature, while bacteria are prokaryotic organisms. Protoctists have a nucleus and other organelles enclosed in a membrane, whereas bacteria lack a defined nucleus and organelles. Additionally, bacteria have a cell wall composed of peptidoglycan, while protoctists may have cell walls made of various materials or lack them altogether.
bacterium are prokaryaotic (no nucleus) while unicelluar (possessing a single cell) are eukaryotes. Although they have a nucleus, they are essentially comprised of only a single cell.
What is the difference between a unicellular and multi?
There is not a difference between bacteriod and bacterium. Both are bacteria.
Bacteria are unicellular organisms, which is to say, a bacterium is a cell. Bacteria differ from the cells of multicellular organisms in that they are generally much smaller and less specialized.
bacteria is plural and bacterium is singular
a bacteria is smaller than an animal
The ONLY difference is that Protozoans are unicellular and animals multicellular
Unicellular is made up of one cell and multi-cellular is made up of many cells.
Animal-like protists are unicellular~
A pathogenic bacterium is alive while a virus is not.
one has many cells and the other has one cell! :-)
