Question

Which type of organism are less efficient?

• A. Multicellular animals
• B. Multicellular plants
• C. Colonial organisms
• D. Unicellular organisms

Answer 1

The correct option is D Unicellular organisms

• Multicellular organisms including plants, animals and some colonial organisms have differentiated cells that in groups perform a specialized function of life. There is a division of labor in the form of tissues and organs for performing life functions.
• Due to this multi-cellular organisms can survive better and are more efficient. Whereas in the case of unicellular organisms there is only a single cell performing all functions of life which makes it less efficient than multi-cellular organisms.
  Hence, the correct option is D.
