Detailed explanation-1: -Explanation: the dots on the endoplasmic reticulum are ribosomes and this type of endoplasmic reticulum are called Rough endoplasmic reticulum . it’s main function is protein synthesis .

Detailed explanation-2: -(In the first diagram in this article, the red dots represent bound ribosomes; endoplasmic reticulum with bound ribosomes is known as rough endoplasmic reticulum.)

Detailed explanation-3: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.

Detailed explanation-4: -The eukaryotic cells generally contain the 80S type of ribosome in the endoplasmic reticulum and as free ribosome in the cytoplasm.

Detailed explanation-5: -Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm.
