Answers
Answer:
One character common in all pteridophyta is absence of ovules.
Explanation:
Pteridophytes are first evolved plants containing vascular system because of that they are also called as vascular cryptogams. These pteridophytes are feather like leaves containing plants. They are differentiated into independent gamophytic and sporophytic generation. Their sporophytic body contains stem, root and leaves. Cambium is absent in the vascular bundles and no secondary growth is present. Reproduction is asexual through specialized haploid sporangia developed at the ventral surface of the sporophylls leaves.
Answer:
Explanation:
One common characteristic among Pteridophytes is that they don't produce ovules and the reason for this is because they are mostly shrubs and herbs and thus seeds are not provided which eliminates the need for producing an ovule.
Therefore, out of all the given options, which are heterospory, protosteal, absence of ovules, and leptosporangiate sporangia, the correct alternative is 'absence of ovules.'
