Directions: In the following questions, a statement of assertion (A) ...
Correct, option C is the correct answer. Assertion (A) is true, spores are unicellular bodies. They are reproductive cells that are capable of developing into a new organism without fusion with another reproductive cell. But Reason (R) is false, the parent body does not simply break up into smaller pieces on maturation. Spores are formed through a process of sporogenesis, in which a diploid cell undergoes meiosis to produce haploid spores. These spores can be produced by both plant and microorganisms. The reason provided is not a correct explanation of the formation of spores.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: Spores are unicellular bodies.
Reason: The parent body simply breaks up into smaller pieces on maturation.
Explanation:
Spores are reproductive structures found in various organisms such as fungi, plants, and bacteria. They are specialized cells that can develop into new individuals under favorable conditions. Let's examine the given assertion and reason:
Assertion (A): Spores are unicellular bodies.
This statement is true. Spores are generally unicellular, meaning they consist of a single cell. They are formed through a process called sporogenesis, where a parent organism produces spores as a means of reproduction. Each spore contains all the genetic information necessary to develop into a new individual.
Reason (R): The parent body simply breaks up into smaller pieces on maturation.
This statement is false. The reason provided does not correctly explain the assertion. Spores are not formed by the parent body breaking up into smaller pieces. Instead, spores are produced by specialized structures within the parent organism, such as sporangia or sporophytes. These structures undergo meiosis, a type of cell division that reduces the number of chromosomes, resulting in the formation of spores.
Conclusion:
Based on the given information, the correct answer is option C: Assertion (A) is true but reason (R) is false. Spores are indeed unicellular bodies, but they are not formed by the parent body breaking up into smaller pieces.
