Which of the following statement is incorrect?

• A. Protista includes unicellular eukaryotic organisms.
• B. Whittaker considered cell structure, mode of nutrition for classifying organisms.
• C. Organisms in Monera and Protista may be autotrophic or heterotrophic.
• D. Monerans have well defined nucleus.

Answer 1

The correct option is D Monerans have well defined nucleus.

Monerans are primitive organisms. i.e they lack a well defined nucleus and membrane bound organelles. Such organisms are called prokaryotes.
Whereas the organisms which posses a well defined nucleus and also have membrane bound organelles are called eukaryotes.
