a) bryophyta
b) pteridophyta
c) gymnosperm
d) angiosperm ​

Answer 1

Answer:

here u r answer please mack my answers as brainlist

Explanation:

[C]

it's gymnosperm because Gymnosperms, therefore, as exemplified by pine trees, are heterosporous. A major distinction we can make between seed plants (gymnosperms and angiosperms) and the non-seed plants (mosses and ferns) is that seed plants are heterosporous and non-seed plants are homosporous

Answer 2

Explanation:

Production of spores of two different sizes and sexes by the sporophytes of land plants is called as Heterospory.  In the evolution of plants, Pteridophyta is intermediate between bryophytes and gymnosperms. All bryophytes are homosporous and all gymnosperms are heterosporous.  Microspores and megaspores is a characteristic feature in the life cycle of a few members of Pteridophyta and all spermatophytes.

So the correct option is 'Pteridophyta, Spermatophyta.'
