Introduction: The cell is the basic structural and functional, as well as the biological unit of all living organisms. Cells may differ in shape but every cell share certain structural as well as functional features: cytoplasm, plasma membrane, and DNA. Moreover, cells possess various organelles, mitochondria, nucleus, and endoplasmic reticulum to perform essential functions that are vital for cell growth.

Explanation of Solution

In the given image, the rough endoplasmic reticulum is prominent to the upper right in the micrograph. The endoplasmic reticulum (ER) is a network of tubes and flattened sacs, and it is involved in protein and lipid synthesis. The endoplasmic reticulum is classified into different types, namely rough ER and smooth ER. The rough endoplasmic reticulum usually possesses ribosomes attached to it and thus involved in protein synthesis.
