Which of the following cells have a less smooth endoplasmic reticulum?

The smooth endoplasmic reticulum (SER) is a membranous network of interconnected tubes and sacs that forms a continuous system throughout the cytoplasm of eukaryotic cells. The SER is abundant in cells that specialise in lipid metabolism.

Almost all eukaryotic cells include the smooth endoplasmic reticulum. However, some eukaryotic cells, such as eggs, embryonic cells, and mature RBCs lack smooth endoplasmic reticulum. Some specialised cells, on the other hand, are high in SER.

Sebaceous glands, gonadal cells involved in the production of steroid hormones (such as Leydig cells in the testis and follicular cells in the ovary), hepatocytes in the liver, and striated muscle cells are examples of cells with high SER.
