angiosperms
seed mosses
seed ferns

20 multiple choice 2 points
which gives rise to the male gametophyte in seed plants?
microsporangia
megasporangia
none of the above
antheridium

Explanation:

1. For the first question, seed - ferns were the first seed - bearing plants to evolve and are now extinct. Gymnosperms and angiosperms evolved later. Mosses do not produce seeds.
2. For the second question, in seed plants, microsporangia give rise to microspores which develop into the male gametophyte. Megasporangia give rise to the female gametophyte, and antheridium is the male sex organ in non - seed plants like bryophytes and pteridophytes.

Answer:

1. Seed Ferns
2. Microsporangia
