Question

The cells in which the hereditary material or the DNA is not surrounded by a membrane are called

• A. Eucaryotic cells
• B. Membrane-less cells
• C. Prokaryotic cells
• D. Cells without nuclei

Answer 1

The correct option is C Prokaryotic cells

A prokaryote is usually a unicellular organism, sometimes a multicellular organism, that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. Prokaryotes are divided into two domains, Archaea and Bacteria. In contrast, species with nuclei and organelles are placed in the third domain, Eukaryota. Prokaryotes reproduce without fusion of gametes. The first living organisms are thought to have been prokaryotes. Prokaryotes have a prokaryotic cytoskeleton, albeit more primitive than that of the eukaryotes. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.

So the correct option is 'prokaryotic cells'.
