Answer:
Step-by-step explanation:
The complete question is
Cells contain specialized parts, known as organelles, to perform
specific tasks, such as waste disposal, protein building, and
movement. Even though these basic cellular functions occur in
all cells,
A. all cells do not perform the same exact functions in
unicellular organisms.
B. the cellular components are not at all related to the overall
function of the cell.
C. the cells in unicellular organisms and all the cells in
multicellular organisms must perform the same functions.
D. all cells do not perform the same exact functions in
multicellular organisms.
Solution -
In multi cellular organism, the cells perform similar function only up to a certain stage of development of organism after which the cells get specialized and become part of different organ system and thus each cell performs a different function. For instance, cells of liver and heart will perform different activities
However, unicellular organism consists of only one cell thus all the essential functions of life are performed by that single cell only.
Thus, option D is correct
