Answer:
Both ferns and flowering plants produce spores at some point in their life cycles. True
Only ferns have a gametophyte as part of their life cycle. False.
Only flowering plants produce pollen grains. true
Both a tree and a large fern plant are diploid sporophytes. True
Explanation:
Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation. Both tree and large fern plants having diploid sporophytes which is a necessary part of their life cycle.
False negative is a condition when you got a negative result for a specimen which was positive. To prevent false negative occur, first you need to use golden standard test or a test with high specificity. You can do multiple tests to ensure the specimen is negative and using a positive control to make sure the reagent is still working fine.
