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.
The grainy appearance of the sun's surface, known as granulation, is caused by the convective motion of gases below the surface. Rising hot plasma carries energy to the surface, creating bright granules, while cooler plasma sinks back down, creating darker areas. This continuous churning process gives the sun's surface a granular texture.
The photosphere is considered the sun's surface because it is the visible layer of the sun that emits light and heat into space. It is where most of the sun's energy is produced and is the layer that we see when we look at the sun.
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.
The sun is a hot ball of glowing gases, primarily composed of hydrogen and helium. It does not have a solid surface, so it does not have a texture like a solid object would. Instead, it emits light and heat due to nuclear fusion reactions happening at its core.

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.

Granules are small convective cells on the Sun's surface caused by rising hot gas and sinking cool gas. Spicules are small jets of gas that shoot upward from the Sun's surface. Together, these features create the granulated texture seen on the Sun's surface.
Electromagnetic waves on the surface of the sun are produced through the process of nuclear fusion in its core. The intense heat and pressure generated by nuclear reactions cause charged particles to move rapidly, creating electromagnetic radiation in the form of light, ultraviolet, and other wavelengths. These waves are then emitted from the sun's surface into space.

Because it's in direct contact with heat produced by the sun.
Granulation occurs in the photosphere, which is the visible surface of the Sun. It is characterized by the pattern of rising and falling material due to convective currents in the outer layer of the Sun.

Sun spots are physical phenomenons produced by difference of tenperatures between various regions of the Sun surface.
The heat generated in the core of the sun is transported to the surface through a process called radiative and convective heat transfer. Energy in the form of photons moves outward through the radiative zone, and in the convective zone, hot plasma rises to the surface carrying heat with it.
