Question

Which one of these structures are more similar in Escherichia coli and Chlamydomonas :

• A. Cell wall
• B. Cell membrane
• C. Ribosomes
• D. Chromosomal organisation

Answer 1

The correct option is B Cell membrane

Both Escherichia coli ( E.coli ) and Clamydomonas have cell membrane.

E.coli are prokaryotic cells with a cell wall. DNA is found in the center in the form of a single circular chromosome. It shows the presence of 70S ribosome.

A Chlamydomonas is a eukaryotic cell without the cell wall, with the 80S ribosome, chloroplast and the nucleus tightly bound and organized chromosomes.

Option B is correct.
