Question

Bobby has labeled the following diagram of a cell. His science teacher tells him it is perfect except for one error. Evaluate the diagram and choose the option that describes how Bobby's diagram can be corrected cell membrane nucleus cell wall cytoplasm The cell membrane should be the outermost layer of the cell The cell does not have a cell wall, only a cell membrane This type of cell does not contain a nucleus This type of cell does not contain cytoplasm.

Answer 1

This type of cell does not have a nucleus because it is a prokaryote.

Answer 2

The answer should be:

This type of cell does not contain a nucleus.

Here is why:

The type of cell that Bobby is looking at is what you call a prokaryote. These are simple unicellular organisms that do not contain a nucleus. They also do not have membrane-bound organelles, so they are just simply floating around the cytoplasm. What that should be labeled as though is nucleoid instead.
