Answer:
The correct answers are: they both have a plasma membrane and protoplasm, and they both have DNA.
Prokaryotes and eukaryotes share many common features some of which are as follows:
1. Cell membrane: Both the cells are surrounded by cell membrane which isolate them from surrounding environment and acts as selective barrier.
2. Genetic material: Both the cells contain DNA as their genetic material which regulates the function of the cells and is passe to the next generation.
3. Ribosomes: Both the cells have ribosomes which help in translation of mRNA in both.
4. Protoplasm: Both the cells contain protoplasm. In eukaryotes protoplasm is divided into cytoplasm and nucleoplasm.
