Multiple Choice
In what kinds of organisms is cell specialization a characteristic feature?
A
All organisms equally, because every cell in every organism forms tissues
B
Viruses, because their capsid proteins differentiate into specialized tissues
C
Multicellular organisms, in which different cell types are organized into tissues with distinct functions
D
Unicellular organisms, because a single cell must specialize into many different tissue types
Verified step by step guidance1
Understand the concept of cell specialization: it refers to the process by which cells develop distinct structures and functions to perform specific roles within an organism.
Recognize that unicellular organisms consist of a single cell that performs all necessary life functions, so they do not have specialized cells forming tissues.
Note that viruses are not considered living organisms and do not have cells; their capsid proteins do not form tissues or specialized cells.
Identify that multicellular organisms have many cells that differentiate into various types, each specialized to perform unique functions, and these cells are organized into tissues.
Conclude that cell specialization is a characteristic feature of multicellular organisms, where different cell types form tissues with distinct functions.
