Accordingly, sex is defined across species by the type of gametes produced (i.e.: spermatozoa vs. ova) and differences between males and females in one lineage are not always predictive of differences in another.
between organisms or reproductive organs of different sexes is not limited to animals; male gametes are produced by and land among others. In land plants, female and male designate not only the female and male gamete-producing organisms and structures but also the structures of the that give rise to male and female plants.
