Question

A stain was developed by a group of scientists to stain a particular cell organelle. The stain was tested on various tissues derived from an autopsy sample from a mammal. The organelles were counted. The results showed maximum number of the organelles in cells of brain, lesser in cells of heart, least in mature sperms, and absent in erythrocytes. Identify the organelle from the following options.
(A) Nissl bodies
(B) Mitochondria
(C) Golgi bodies
(D) Endoplasmic reticulum​

Answer 1

Answer:

It is nissl bodies which synthesis protien .

It is present in neuron.

Hope it is helpful for you...

Answer 2

The correct answer is (A) Nissl bodies.

Explanation:

• Nissl bodies are located in the neurons.
• These are granular structures having high concentration of Rough Endoplasmic Reticulum (RER) and free ribosomes.
• They form the location where proteins are synthesised in the neurons.
• They are mainly localised in the cell body of the nucleus.
• Heart and brain contains high concentration of mitochondria as they need high amount of energy.
• Mature erythrocytes lack most of the organelles as it utilises most of its space to carry oxygen bound to haemoglobin molecules.
