Answer: Both are true
Explanation:
Assertion (A) is correct because many fungal spores are encased in a protective structure called a cyst which helps protect the spores from desiccation, physical damage, and other environmental stresses.
Reason (R) supports assertion (A) by explaining that fungal spores are often dispersed and remain suspended into the air until they encounter a suitable substrate for germination and growth. The cyst helps ensure the spores' viability during this dispersal phase.
