Sponges are multicellular organisms belonging to the phylum Porifera, characterized by a porous body structure and the presence of specialized cells called choanocytes that facilitate water filtration and nutrient absorption. In contrast, flagellate protists are unicellular eukaryotes that possess one or more flagella for movement and feeding, and they lack the complex tissue organization found in sponges. While sponges rely on a simple body plan for nutrient acquisition through water flow, flagellate protists actively swim to capture food particles. Thus, the key differences lie in their cellular organization, complexity, and feeding mechanisms.
Euglena, which is a genus of unicellular flagellate protists.
Animal-like protists are autotrophic, while plant-like protists are heterotrophic.
One piece of evidence supporting the idea that poriferans evolved from protists is the similarity in genetic sequences between certain protists and sponges. Additionally, some protists share characteristics with poriferans, such as the presence of collar cells, which suggests a possible evolutionary relationship between the two groups. Studies of early fossil records also provide some evidence of a transitional form between protists and sponges.
Protists are the miscellaneous group out of the six kingdom, so as long as they are eukaryotic they are protist. They can be heterotrophs or autotrophs, they can be multicellular or single-celled
Finish the question. Which organisms are listed?
Eglena is a flagellate protists that is unicellular.
Euglena, which is a genus of unicellular flagellate protists.
Multi-cellular animals also called metazoans came from protists which were colonilized. These colonies of protists formed hollow spheres. These protists which were linked together into a hollow sphere may have had some form of specialization to then make tissue.
Protists don't have specialized tissues
Protists do not have specialized tissues.
Animal-like protists are autotrophic, while plant-like protists are heterotrophic.
They are Eukaryotes
They are less complex

They are less complex
they r sexual...because the reproductive organs in the male and female sponges differ from one another
