Spore formation - Spore formation is generally seen in bacteria and most fungi. Spores are unicellular bodies, formed by the parent organism to carry out reproduction. If environmental conditions are suitable, the spore will develop into a new individual. Spores come in a wide variety of forms and are produced and dispersed in many different ways. Spores are very effective, because they are small and light, and so can be carried by wind, water or animals; so they can travel far away from the parent, perhaps to better conditions.

Assertion and Reason Type Question Explanation:
Assertion: Spores are unicellular bodies.
Reason: The parent body simply breaks up into smaller pieces on maturation.
The correct answer is option (c) Assertion (A) is true but reason (R) is false.
Explanation:
- Spores are unicellular bodies: This assertion is true. A spore is a reproductive structure that is adapted for dispersal and survival in unfavorable conditions. Spores are produced by many organisms, including plants, fungi, and bacteria. They are often small and unicellular, and can be dispersed by wind, water, or other means.
- The parent body simply breaks up into smaller pieces on maturation: This reason is false. Spores are not formed by the fragmentation of a parent body. Instead, they are produced by a specialized process of cell division called meiosis. In this process, a diploid cell divides into four haploid cells, each of which can develop into a new organism under favorable conditions.
Therefore, option (c) is the correct answer.
