Convection
This effect on the suns photosphere is from large cells or grains which are about 100 km accross. There is hotter rising gas at the centre with falling cooler gas at the edge of these cells, which are constantly shifting every few minutes. These cells or grains are contained within much larger structures called super granules, which are around 30,000 km in size and last for several hours.
The layer is the photosphere. (Granular cells on the Sun are the tops of convection current cells.)
The evidence in the photosphere of the type of energy transport occurring beneath it is mainly through the observation of granulation patterns. Granules are the tops of convective cells that transport energy from the interior of the Sun to its surface. The size and shape of these granules give insights into the convective processes happening beneath the photosphere.
The circulation pattern cells near the equator are the Hadley cells. These cells involve warm air rising near the equator, moving towards the poles at upper levels of the atmosphere, cooling and sinking around 30 degrees latitude, and returning towards the equator near the surface. This creates a continuous loop of air movement in the tropical regions.
A solar granule is typically around 1,500 kilometers (about 930 miles) in diameter. These granules are the tops of convective cells in the solar surface where hot plasma rises and cool plasma sinks, creating the granular pattern seen on the Sun's photosphere.
The bubbling characteristic of the photosphere is called solar granulation. These granules are caused by the convective motion of plasma beneath the surface of the Sun, creating cells of rising hot plasma and sinking cooler plasma that appear as granules on the photosphere.

The layer of the Sun's atmosphere composed of super granular cells is called the photosphere. These cells are convection cells that transport heat from the interior of the Sun to the surface. The photosphere is the visible surface of the Sun where the majority of its light is emitted.
Those are called granules. Granules are small convection cells on the surface of the sun, caused by hot gas rising and cooler gas sinking. They are typically about 1000 kilometers in diameter and last for about 5 to 10 minutes.
PHOTOSPHERE
The layer of the Sun's atmosphere that is composed of granular and super granular cells is the photosphere. These cells represent convection currents that transport heat from the Sun's interior to its surface. The granular cells are larger convection cells, while super granular cells are groups of smaller granules.

The photosphere is the visible surface of the Sun, which appears as granules (the tops of convection cells). The "supergranules" are a pattern into which the granules may be clumped, and can be considered either structurally part of the photosphere or part of the convection zone that lies directly beneath it. Some sources extend the term "supergranulation" to include both the photosphere and the chromosphere (which does not, however, use convection).

The layer of the sun's atmosphere composed of granular cells is the photosphere. This is the visible surface of the sun where energy is emitted in the form of light and heat. Granular cells are convective cells of gas that transport heat from the sun's interior to the surface.
