Question

Refer to the Nested Venn Diagram above. Identify the Venn diagram section(s) which include(s) prokaryotic cells.

Answer 1

Prokaryotic Cell Structure. Prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do. Instead, prokaryotic cells have a nucleoid region, which is an irregularly-shaped region that contains the cell's DNA and is not surrounded by a nuclear envelope. The Prokaryotic Cell. Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

I believe the answer is B.

B) II, III, IV

Answer 2

Answer:

The correct answer will be option-A.

Explanation:

The prokaryotes are primitive cells formed in the primordial period which shows characteristic differences from eukaryotes.

Prokaryotes contain their DNA in the cytosol as they lack nucleus as well as they also lack cytoplasmic organelles like mitochondria, ER, Golgi bodies and others.

In the given question option-I is correct as the prokaryotes contain the fluid substance called cytoplasm enclosed in a cell membrane with its genetic material in the cytosol and a protein synthesis machinery called ribosomes.

Thus, option-I is the correct answer.
