Does a seed need sun to grow?

In a way, yes. Some seeds germinate only when covered with soil, but the actual triggering mechanism depends on the wavelength of light reaching the seed. Seeds that germinate in "darkness" require long wavelength light to do so, ie. heatwaves. Seeds that grow on the surface need short-wave light to start germination.
