A: Cells use energy in order to grow, regulate metabolism and reproduce. This energy is obtained from a source such as food molecules or light from the sun, and through processes like glycolysis, the citric acid cycle and oxidative phosphorylation, an energy-rich molecule is then created.
We can also change the sunlight directly to electricity using solar cells. Solar cells are also called photovoltaic cells â or PV cells for short â and can be found on many small appliances, like calculators, and even on spacecraft.They were first developed in the 1950s for use on U.S. space satellites.olar energy can also be used to make electricity. Some solar power plants, like the one in the picture to the right in California's Mojave Desert, use a highly curved mirror called a parabolic trough to focus the sunlight on a pipe running down a central point above the curve of the mirror.
