How are the cells in multicellular organisms different from those in single-celled organisms?
Mrac [35]

Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.

Explanation:

Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc

From the examples given, the cells of multicellular organisms are specialized in function in that:

- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces

On the other hand, unicellular organisms possess just one cell that do all the functions.

Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
