In prokaryotes, what is the name of the permeable boundary around the cell?

Answer explanation

In the Wiley tutorial you may have seen the answer as mesosome. Mesosomes are infolding of the cell membrane. The cell membrane is the permeable boundary of the cell itself.

In prokaryotes, what part is the site of protein synthesis?

In prokaryotic cells, which part stores genetic material?

• nucleus

• ribosome

• nucleoid region

• nucleolus

Answer explanation

In prokaryotic cells the single strand of DNA, genetic material, is found at the nucleoid region without any container such as a nucleus.

In prokaryotic cells, what part protects the cell against mechanical and hypertonic stress?

Answer explanation

Yes, plants have cell walls that serve the same function!

• golgi apparatus

• smooth endoplasmic reticulum

• vacuole

• ribosome
