Bacterial Cell Structure

Bacterial cells are much smaller than animal and plant cells. They are prokaryotic and lack a true nucleus.

Do you know where the DNA is stored?

What is Bacterial Cell Structure?

"Bacterial cells are small prokaryotic cells that lack a nucleus and membrane-bound organelles, instead having a single loop of DNA and plasmids."

Question 1

Which statement about bacterial cells is correct?

Question 2

How do bacterial cells usually compare in size with plant and animal cells?

Question 3

In a bacterial cell, what are plasmids?

The genetic material is not enclosed in a nucleus, but exists as a single DNA loop.

They may also contain small rings of DNA called plasmids.

Exam Tip

Bacterial cells have a cell wall, but it is NOT made of cellulose (unlike plant cells).

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
