Question

Quizplus · Accepted Answer

All living organisms are made of cells. However, only a minority of them are eukaryotes with defined cell nuclei. Not all cells obtain their energy directly from sunlight. However, regardless of the energy source, the main energy currency used by all known living cells is ATP. Some prokaryotic genomes contain only a few hundred genes.
