Hint:Prokaryotic cells lack all membrane-bound organelles. This is because they are primitive in nature. They originated way before eukaryotes.

Complete answer: The main difference between the prokaryotic and eukaryotic cells is the membrane-bound organelles. The prokaryotes lack membrane-bound organelles like chloroplasts, mitochondria, well – defined nucleus, etc. So, according to the question, options B, C, and D are completely ruled out. This is because these structures are absent in prokaryotes.

Therefore, the answer is option A. Both prokaryotic and eukaryotic plant cells have a cell wall.

Additional information:
The prokaryotic cell lacks a well–defined nucleus. The nuclear material is present at the center of the cell and it is called a nucleoid.
Apart from the absence of membrane-bound organelles, there are some more differences between prokaryotic and eukaryotic cells. The prokaryotic cells have a circular structure of genetic material while the eukaryotic cells have a linear structure of their genetic material.
The ribosomes of prokaryotes are the 70S while that of eukaryotes are 80S. S stands for Svedberg’s coefficient.
Apart from this, prokaryotes are always unicellular while eukaryotes can be either unicellular or multicellular. The cellular structure of prokaryotes is very simple as compared to eukaryotes. Plant cells are even more complex or more modified as compared to animal cells. These differences in structure and in function were observed by scientists and they gave the Five Kingdom Classification based on these.

Note: The presence of a cell wall is a feature of plant cells and some prokaryotes which make their own food. The cell wall is protective in nature. It also provides strength to the cell.
