Which of the following Illustrations shows the mitochondrion’s structural details?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. b.
The image b depicts the typical bean-shaped structure of a mitochondrion, with its outer and inner membranes. The inner membrane is folded into cristae, which increase the surface area for cellular respiration. The matrix, the space enclosed by the inner membrane, is also visible.
The other options do not accurately represent the structure of a mitochondrion.
Option (a): This image depicts a simple pattern of circles, which does not resemble any cellular structure, let alone a mitochondrion. It's a basic pattern without any biological significance.
Option (c): This image shows a brick-like pattern, which might remind one of a cell wall or a tissue layer. However, it lacks the characteristic features of a mitochondrion, such as the double membrane and the cristae.
Option (d): This image represents a molecular structure, possibly a carbohydrate or a lipid molecule. While it's a biological molecule, it's not the structure of a mitochondrion. Mitochondria are organelles, and their structure is much larger and more complex than a single molecule.
Therefore, among the given options, only option (b) accurately depicts the structural details of a mitochondrion.
