Endoplasmic reticulum was discovered by Porter et al using electron microscopy.

Myeloid bodies and nissl granules are believed to be formed from endoplasmic reticulum.

The enzyme nucleotidase is present on the cytoplasmic surface of endoplasmic reticulum.

Endoplasmic reticulum is not found in mature erythrocyte. So, this is the correct answer.

Glucose 6-phosphatase is present on the luminar surface of the endoplasmic reticulum.

A membrane lined system of channels present throughout the cytoplasm is called endoplasmic reticulum. So, this is the correct answer.

Correct answer. The endoplasmic reticulum without attached ribosomes is called a granular or smooth endoplasmic reticulum.

Correct answer. Endoplasmic reticulum was discovered from liver cells.

Correct answer. Rough endoplasmic reticulum is found abundantly in pancreatic acinus cells.

Correct answer. Detoxification of pollutants, carcinogens and drugs is carried out by P-450 and P-448 present on smooth endoplasmic reticulum.

Correct answer. Rough endoplasmic reticulum has more cisternae than smooth endoplasmic reticulum.

Smooth endoplasmic reticulum is found abundantly in muscle cells. So, this is the correct answer.

Correct answer. In muscle cells, endoplasmic reticulum is known as sarcoplasmic reticulum.

Endoplasmic reticulum is present in liver cells.

Correct answer. Endoplasmic reticulum is made of tubules (branched network; 50-100 nm in diameter), cisternae (parallel interconnected flattened sac of 40-50 nm of thickness) and vesicles (round or oval; 25-500 nm diameter).
