Answer:
D. Most cells have a membrane, but some don't
Explanation:
A clear indicator that eliminates the first two options is that not all cells are alike, meaning that they can be different kinds of cells that are different sizes. For example, you can take prokaryotic cells and eukaryotic cells. These two types vary in their structure, such as how one no nucleus and the other does. Even in eukaryotic cells, there are differences in each type of eukaryotic cell, such as how plant cells have a square-like shape and animal cells have a more circular shape, meaning that cells can come in different shapes and have different sizes too.
All cells do not need a nucleus, as prokaryotes survive perfectly fine with their DNA floating around in the cytoplasm, which proves that C is not one of the answers. However, unlike the nucleus, both prokaryotes and eukaryotes, the two domains that all living organisms will belong to, have a membrane, meaning that all organisms, bacteria, archaea, etc. WILL have to have a membrane to survive.
Not only this, because using logic, the membrane is responsible for controlling what comes in and out of the cell, which is necessary for the survival and therefore means that all cells would need this to live. Therefore, the answer to this question is D because all cells need a membrane.
Hope this helped somewhat!! :D
I would appreciate if you told if the answer was correct and if the explanation makes sense though! ;(
