Protozoans like paramecium have protoplasmic invasions called gullets, which aid in these species' food uptake and digesting.
<h3>What are protists?</h3>
Protists have eukaryotic cells, as opposed to bacteria, these organisms feature cytoplasmic membrane-bound components as well as a nucleus that is membrane-bound.
Another kind of protists is zooflagellates, they resemble animals and use flagella to move. Flagella are whip-like organelles that rapidly spin and help an organism move through the water like a boat's propeller.
The majority of zooflagellates have one to eight flagella that aid in movement, protists do not belong to a monophyletic group of creatures.
Therefore, The paramecium's gullet functions as the buccal cavity where food is transformed into food vacuoles for digestion.
