Which statement correctly compares protists to prokaryotes?
The cells of protists and prokaryotes contain nuclei.
The cells of protists have cell walls, but prokaryotes do not.
Both protists and prokaryotes are multicellular.
Most protists and all prokaryotes are unicellular.Which statement correctly compares protists to prokaryotes?

Most protists and all prokaryotes are unicellular.
The correct statement that compares protists to prokaryotes is that most protists and all prokaryotes are unicellular.
The correct statement that compares protists to prokaryotes is:
"Most protists and all prokaryotes are unicellular."
To understand this comparison, let's break it down. First, let's define protists and prokaryotes.
Protists: Protists are a diverse group of eukaryotic microorganisms. They can be either unicellular or multicellular. Examples of protists include amoebas, paramecia, and algae.
Prokaryotes: Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They include bacteria and archaea.
Now, let's examine the options provided:
1. The cells of protists and prokaryotes contain nuclei: This statement is incorrect. While protists are eukaryotic and have a true nucleus, prokaryotes lack a nucleus. Therefore, only protists have cells that contain nuclei.
2. The cells of protists have cell walls, but prokaryotes do not: This statement is also incorrect. While some protists do have cell walls, not all of them do. On the other hand, prokaryotes can have cell walls made of peptidoglycan, which provides them with structural support.
3. Both protists and prokaryotes are multicellular: This statement is incorrect. Protists can be either unicellular or multicellular, while prokaryotes are always unicellular.
4. Most protists and all prokaryotes are unicellular: This statement is correct. The majority of protists are indeed unicellular, although there are some exceptions. In contrast, all prokaryotes are unicellular.
Therefore, the correct statement is: "Most protists and all prokaryotes are unicellular."
