Final answer:
Cells and viruses share some common structures, but there are also significant differences between them.
Step-by-step explanation:
Cells and viruses have some structures in common, although there are significant differences between them.
All cells, whether prokaryotic or eukaryotic, have a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane is a phospholipid layer that surrounds the cell, while ribosomes are involved in protein synthesis.
On the other hand, viruses consist of a nucleic acid core, an outer protein coating called a capsid, and sometimes an outer envelope derived from the host cell. They lack organelles, ribosomes, and a plasma membrane like cells do.
