they are unicellular
Both have a cell wall
Bacteria are divided into two domains, Archaea and Bacteria, based on genetic and biochemical differences. Archaea have unique characteristics that distinguish them from traditional bacteria, such as operating in extreme environments. This separation helps scientists classify and study these organisms more effectively.
They lack a nucleus. They are prokaryotes. They are unicellular.
Protists and bacteria are grouped into different domains because the Protists are more complex and contain a membrane backed nucleus which bacteria lacks. Furthermore, Protists eat bacteria and bacteria decomposes Protists. Bacteria is not made of cells and Protists are photosynthetic.
they both grow. and, neither get their food by photosynthesis.
bacteria is still around and it was one of the first living organisms
they look similar, they have similar DNA, they are both very ancient organisms, they both perform the same ecological function
Microfossils are fossilized remains of single-celled organisms similar to modern bacteria. They exist in rocks that are more than 3.5 billion years old.
All living organisms' bodies are made to reproduce. For example, plants pollinate, terrestrial organisms have penis' and vaginas and even bacteria multiply a-sexually.
The biological term "prokaryote" (plural prokaryotes) refers to bacteria or similar organisms lacking cell nuclei.
Unicellular organisms: some bacteria, spermatozoa. I think also diatoms and similar planktonic fauna.
