Answer:
Fern spores are unable to resist prolonged dry conditions.
Step-by-step explanation:
Ferns are the vascular plants that reproduce by the formation of spores. Ferns are commonly not found in deserts but mostly inhabit swamps, marshes, moist woodlands. Ferns form spores in sporangia and bursting of sporangia discharge spores. These spores are not able to withstand the dry conditions for a long time and die under a prolonged scarcity of water. Ferns also use water as a transport medium to transport the sperms to the neck of an archegonium.
