Reptilian embryos are protected from desiccation by a leathery shell. Similarly, sporophytes of both gymnosperms and angiosperms protect embryos within ________, and they also protect male gametophytes against desiccation using ________.
1. pollen grains; waxy cuticle
2. fruits; stamens
3. ovaries; filaments
4. seed coats; sporopollenin
5. ovules; waxy cuticle
I don't think the answer is 1 or 2. Please help
How do seed plants protect their embryos?
but i think is 4, because the question is ask protect embryo, fruit is only present in angiosperm not in gymno.. and the fruit is no function for protected form dessication,
