Respuesta :
pollen....because cones are absent in angiosperms.....flowers are absent in gymno....and seeds are also absent in gymno sperm........so and is pollen !
The right answer is all of them (these elements concern either gymnosperms, angiosperms or both of them).
Angiosperms and gymnosperms are seed plants (spermaphytes).
Pollen is the means of transport of male gametes in spermaphytes.
Gymnosperms and angiosperms use reproductive system (cones for gymnosperms and flowers for angiosperms)
