The following statements refer to a comparison of reproduction in ferns vs. flowering plants. Indicate whether each statement is
true or false by writing true or false in each blank. true Both ferns and flowering plants produce spores at some point in their life cycles. false Only ferns have a gametophyte as part of their life cycle. Only flowering plants produce pollen grains. true Both a tree and a large fern plant are diploid sporophytes.
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.
