Yeah, the last time this was posted I had to run to wikipedia because I was fuming at my memory being wrong. I even have vague memories from biology in college about the 8-cell formation of a fertilized plant ‘egg.’ The poster was likely trying to say that many plants don’t have ‘male-only’ and ‘female-only’ types, but at the very least, fruit bearing plants/trees (angiosperms, if I remember) have two sperm-equivalents in the pollen that drill down into the pistil of the flower and find the waiting gamete. One fertilizes, one becomes the food portion that we take sustenance from.
