how do cells behave in a multicellular protist

Other examples of multicellular protists include seaweeds, such as red algae and green algae. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. The evolution of multicellular life from simpler, unicellular microbes was a pivotal moment in the history of biology on Earth and has drastically reshaped the planet's ecology. They're missing mitochondria. At long last, we return to the exploration of multicellularity that was started a few weeks ago. This study is called Epigenetics, whic. For example, protozoans are grouped as animal-like . Which group of protists consumes CO2 and produces O2 for much of Earth, serving as the base of food webs in lakes, streams, and the oceans? B. A) We both can move. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia. Although the majority of protists are unicellular, some are multicellular organisms. -bacteria are prokaryotic and protists are eukaryotic. This aggregation of cells is then followed by the development of an aerial multicellular structure, known as a fruiting body or sorocarp. The organism has some impressive features. 2.They exhibit cell specialization. They don't exhibit cell specialization. Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. Algae is the small, plant matter found living in both freshwater and marine environments. Multicellular protists, however, do not show cellular specialization or differentiation into tissues. However, some protists may behave like animals or plants. Genetic diversity. However, in scenarios of cooperation, there are constantly tempting opportunities "for cells to shirk their duties — that is, cheat," Libby said. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism.
