Question

Resolution power is the ability to

• A. distinguish two close points
• B. distinguish two close objects
• C. distinguish amongst organelles
• D. magnify image.

Answer 1

The Correct Option is B

The question involves the concept of resolution power in the context of microscopy, which is a key topic in the field of biology. Let's delve into the details to clarify why the answer is "distinguish two close objects".

Understanding Resolution Power:

• Resolution Power: In the context of microscopy and optics, resolution power refers to the ability of an optical instrument to differentiate between two points that are close together as separate entities. It is fundamentally the measure of clarity of the instrument in distinguishing detailed aspects of the objects being observed.
• The higher the resolution power, the closer two objects can be while still being differentiated clearly.

Explanation of Options:

• Distinguish two close points: While resolution power indeed involves distinguishing close entities, the term "points" is typically more relevant to pure geometry rather than practical observations in microscopy.
• Distinguish two close objects: This option is correct. In microscopy, resolution power specifically pertains to the ability to distinguish two separate objects that are in close proximity to each other.
• Distinguish amongst organelles: Although microscopes are used to observe organelles, distinguishing amongst organelles is more specific and involves understanding biological functions rather than resolution power alone.
• Magnify image: Magnification is a separate concept. It is about enlarging the appearance of an object, but does not relate directly to resolution power, which is about clarity and distinction.

Therefore, the correct answer to the question regarding resolution power in microscopy is to distinguish two close objects.
