First plants to reproduce bisexually It is surprising how many people are not aware, even today, that plants reproduce bisexually in many species. In fact the plants have been at it a long time. Algae first began to reproduce bisexually around 1,000,000,000 years ago. Considering that man has been copulating for a million years or so, the various species of algae score high on persistence. A freshwater algae (Ulothrix) is often used to illustrate the origin of gametes, i.e. the origin of sex cells. The elongated filament-body of the algae generates a number of small spores which have lost the capacity to germinate (as they do in asexual reproduction): the spores come together and fuse to form a new individual - one of the simplest instances of the sex act.
