The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates, which decorate both the proteins and lipids and help cells recognize each other. Hope this helps :)

Answer:
Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes.
Explanation:
DNA, cell membrane, cytoplasm, and ribosomes.
Both prokaryotic and eukaryotic cells have structures in common. All cells have a cell membrane, ribosomes, cytoplasm, and DNA. The cell membrane, or plasma membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
