Question

Why does rough endoplasmic reticulum look rough under a microscope?

Answer 1

Endoplasmic reticulum:

1. A network of small, tube-like compositions presents within the cytoplasm is the endoplasmic reticulum.
2. It is a membrane-bound organelle found only within the eukaryotes.
3. The endoplasmic reticulum comes in two forms, that is, rough endoplasmic reticulum and smooth endoplasmic reticulum.
4. When the endoplasmic reticulum bears proteins producing compositions called ribosomes, it is known as the rough endoplasmic reticulum.
5. In the presence of ribosomes, the endoplasmic reticulum looks rough under the microscope and thus is known as the rough endoplasmic reticulum.
6. The rough endoplasmic reticulum is primarily involved in the production of proteins and is found mostly on the nucleus’s outer membrane.
7. When the ribosomes are not present in the endoplasmic reticulum, it looks smooth under the microscope and is thus known as the smooth endoplasmic reticulum.
