The grains are called granules. They are convective cells. Extra hot plasma rises near the center of each granule while lower temperature plasma sings at their edges.
The sun's surface has a grainy texture due to the presence of convection cells known as granules. These granules, which are typically about 1,000 kilometers in diameter, form as hot plasma rises to the surface, cools, and then sinks back down, creating a pattern of bright and dark areas. This process is driven by the sun's turbulent convection zone, where energy is transferred from the interior to the surface. The granulation effect is a key feature of solar dynamics and contributes to the sun's overall appearance.
The grainy texture on the sun's surface produced by numerous bright markings is called granulation. These granules are the tops of convection cells, where hot plasma rises and cooler plasma sinks in the sun's outer layer.
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
They appear in the Photosphere. That's basically the "surface" of the Sun.
Sunspots appear on the surface of the Sun, specifically in the photosphere. These darker, cooler areas are caused by magnetic activity on the Sun's surface. Sunspots can vary in size and shape and are often seen in groups.

The bright markings are "faculae" (plural of facula). However, I wouldn't say that they produce the grainy texture. I think the "granulation" is there even without the faculae.

The shadow of an airplane will appear on the line between the sun and the airplane and on the nearest visible surface directly opposite the sun.
Raw photos may appear grainy because they capture more detail and information from the camera sensor, including noise and imperfections. This can result in a grainy or textured appearance in the image.
Sunspots are actually the colder regions on the sun's surface, due to which comparatively less radiations are emitted by these regions than the rest of the surface of the sun. That is why they appear to be black.

The surface of the sun is not actually grainy but i will give you a little insight into why it looks like that. If you have ever lit a large fire and let is burn down a little, when you look at the embers or deeper into the fire, you can see different colours, ranging from white through yellow, orange, red to black with varying degrees and shades. The Sun is similar to this but on a much more massive scale, when a snap shot is taken its looks grainy because of all the variations, but if you saw a motions movie of the suns surface it is an undulating mass of colours.Look at the related source videos and links below for comparison.
