It is misguided to try to find our eukaryotic ancestor among modern-day protists because the Protists living today have been through a process of evolution just as extensive as the one that produced every other living organism.
As the name might imply, Eukarya is the name for eukaryotes.
Protists, with the exception of algae, are unicellular.
Black truffle is a eukaryote. Eukaryotes are organisms whose cells have a nucleus and other membrane-bound organelles. They belong to the domain Eukarya, which includes animals, plants, fungi, and protists.
Protists are eukaryotic organisms that are not plants, animals, or fungi. They are typically single-celled but can also be multicellular. Protists have diverse metabolic and reproductive strategies, and some can be both autotrophic and heterotrophic.
An organism with cells containing a nucleus is called a eukaryote. Eukaryotic cells have a membrane-bound nucleus that houses their genetic material, distinct from prokaryotic cells, such as bacteria, which lack this structure. Examples of eukaryotic organisms include plants, animals, fungi, and protists.
Prokaryote
eukaryote.
Prokaryote
Euglena (and other protists) are Eukaryotic
They are less complex
No, protists are eukaryotes.
animals, fungi, protists, and some bacteria
Protists, plants, animals, and fungi are the eukaryotes
Colonial protists
Most importantly,they have an organized nucleus which is lacked in prokariyotes.
Yes all eukaryote cells have ER including, plants, animals, fungi, and protists.
The protists amoebae and paramecium are both eukaryote microorganisms. Especially in the sense that you need a light microscope to see them.
