Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.

a chemical element or substance required in trace amounts for the normal growth and development of living organisms.
The domain Eukarya evolved from the unicellular organisms, and the proof of this can be derived from the endosymbiotic theory. According to this theory, the organelles, such as mitochondria and chloroplasts were previously free-living organisms. This is supported by the fact that the mitochondria and chloroplasts have their own DNA (deoxyribonucleic acid).
Hence, the answer is 'Option C - mitochondria and chloroplasts have their DNA.'
