Detailed explanation-1: -Photosphere-The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.
Detailed explanation-2: -The photosphere is the lowest layer of the solar atmosphere. It is essentially the solar “surface” that we see when we look at the Sun in “white” (i.e. regular, or visible) light. When we observe sunspots and faculae (bright little cloud-like features) we are observing them in the photosphere.

Granules are cells of plasma that are 1000 km in diameter with hot rising plasma in the centre and the cooler plasma laying in the narrow spaces between them.
