Question

Organisms which have cells with no distinct nucleus is/are:

• A. Bacteria
• B. Cyanobacteria
• C. Angiosperms
• D. Both A and B
  

Answer 1

The correct option is D Both A and B

• The kingdom Monera comprises prokaryotic organisms.
• The bacteria and cyanobacteria are included under the kingdom Monera.
• The prokaryotes do not have well-developed cell organelles such as mitochondria, ribosomes, Golgi bodies, etc.
• They also lack a well-defined nucleus and so, the nuclear membrane is also absent. DNA is the genetic material that is present in the cytoplasm.
• Angiosperms are included in the plant kingdom and are made up of eukaryotic cell structures.

Thus, the correct answer is option C.
