You should have learned it in class!
cell specialization
True
Euglena is a protist that can exhibit both autotrophic and heterotrophic characteristics. It has chloroplasts like autotrophic organisms for photosynthesis, but can also feed on organic matter for energy like heterotrophs.
A protist that acts like an animal is called a protozoan. Protozoa are single-celled eukaryotic organisms that exhibit animal-like behaviors such as hunting, moving, and consuming prey.
No, protozoa are single-celled organisms that exist independently as individuals rather than forming multicellular colonies. They are part of the protist kingdom and exhibit a diverse range of structures and behaviors as single-celled organisms.

Multicellular organisms, particularly animals, exhibit the most specialization. Within these organisms, specific cells and tissues have evolved to perform distinct functions, allowing for complex processes such as digestion, respiration, and locomotion. For example, mammals have specialized cells like neurons for signaling and muscle cells for movement, showcasing a high level of functional differentiation. This specialization enables these organisms to adapt to diverse environments and perform intricate biological tasks.
Rhizopoda Sarcodina are animal-like organisms. They are part of the protist kingdom and exhibit characteristics such as heterotrophic nutrition and typically motile.
An example of an animal-like protist is a protozoan such as Paramecium or Amoeba. These single-celled organisms exhibit animal-like behaviors such as actively seeking and consuming food, moving using cilia or pseudopods, and reproducing through binary fission.
The term used to describe organisms composed of identical and unspecialized cells is "colonial organisms." These organisms consist of groups of genetically identical cells that work together, yet they do not exhibit specialization like multicellular organisms. Examples include certain types of algae and some marine invertebrates.
A protist kingdom refers to a diverse group of eukaryotic microorganisms that do not fit into the plant, animal, or fungi kingdoms. These organisms can be unicellular or multicellular and exhibit a wide range of structures and functions. Examples of protists include amoebas, algae, and protozoa.
A multicellular organism is an organism composed of many cells working together in a coordinated manner to perform specific functions. Examples include plants, animals, and fungi. This cellular specialization allows multicellular organisms to carry out complex processes and exhibit higher levels of organization than single-celled organisms.
Bacteria are prokaryotic organisms while protists are eukaryotic. Bacteria are generally unicellular, while protists can be unicellular or multicellular. Protists have more complex cellular structures and are typically larger in size compared to bacteria. Additionally, protists exhibit more diverse modes of nutrition and reproduction compared to bacteria.
