Question

how does the way life functions are carried out differ between unicellular and multicellular organisms? a single cell performs all functions in a unicellular organism, while different cells have specific functions in a multicellular organism. unicellular organisms do not need energy, while multicellular organisms do. unicellular organisms cannot reproduce, while multicellular organisms can. unicellular organisms are all bacteria, while multicellular organisms are all animals.

Explanation:

• Unicellular organisms have a single cell that performs all life functions.
• Multicellular organisms have different cells with specific functions.
• All organisms (unicellular and multicellular) need energy.
• Unicellular organisms can reproduce (e.g., by binary fission).
• Unicellular organisms are not all bacteria (e.g., amoeba is a protozoan unicellular organism) and multicellular organisms are not all animals (e.g., plants are multicellular).

Answer:

A. A single cell performs all functions in a unicellular organism, while different cells have specific functions in a multicellular organism.
