Question

R.E.R is
A.Neutrophilic
B.Acidophilic
C.Basophilic
D.Neurogenic

Answer 1

Hint: The endoplasmic reticulum is a member of cell organelles and a large network of membrane-bound tubules and sheets. It is similar to the plasma membrane. The types of endoplasmic reticulum are- Rough endoplasmic reticulum and Smooth endoplasmic reticulum.

Complete answer:
In an average animal cell, the endoplasmic reticulum typically constitutes more than half of the total animal cell. The endoplasmic reticulum is organized as a net-like labyrinth of branching tubules and flattened sacs that are extending throughout the cytosol. The ER forms a continuous sheet enclosing a single internal space as all the tubules and sacs are interconnected. And that convoluted space is called the Endoplasmic Reticulum Lumen. The ER membrane mediates the selective transfer of molecules between the ER lumen and cytosol.

The rough ER has ribosomes, which are the sites of protein manufacture. The proteins, which are manufactured, are transported to different organisms using the ER. The smooth ER is the site of the manufacture of lipids or fat molecules. Some lipids and proteins help in building the cell membrane whereas some function as enzymes and hormones. It also plays a crucial role in detoxifying poisons and drugs.

As the Rough ER has ribosomes,(stained with basic dyes) this gives basophilic staining to the cytoplasm in H & E stains. It is basophilic because of the presence of RNA content.

Hence the correct answer is OPTION(C)

Note: It also serves as channels for transporting materials like proteins to various organs. It also provides a surface for biochemical activities of the cell and thus functions as a cytoplasmic framework.
