Which one among the following statements is correct ?

Result
Your answer: —  Â·  Correct: B
Explanation

The cell membrane is a fundamental structure present in both plant and animal cells, serving to enclose the cytoplasm and regulate the entry and exit of materials [2]. Statement 1 is incorrect because prokaryotic cells lack a well-defined, membrane-bound nucleus; instead, they contain a nucleoid region [1]. Statement 3 is false as mitochondria and chloroplasts are characteristic membrane-bound organelles found specifically in eukaryotic cells, with chloroplasts being present in plant cells. Statement 4 is incorrect because ribosomes are universal structures required for protein synthesis and are found in both prokaryotic and eukaryotic cells, although they differ in size (70S in prokaryotes versus 80S in eukaryotes). Therefore, only the presence of the cell membrane in both plant and animal cells is a correct statement.
