7) The anthers of a flower are the male reproductive organ on the top of the stamen, which produce pollen. Pollen is the male gametophyte (sex cell). So [B. Male parts that contain pollen] is the correct answer.

8) The location of the female gametophyte (egg, sex cell) is quite different between Gymno - and Angiosperm. The derivation of their name all but gives the feature away: "gymno" means naked seed, of conifers, and "angio" means flower. So the correct answer is [A. In gymnosperms it is within a cone, and in angiosperms it is within a flower].
