Why did most plants end up being hermaphrodites while most animals end up with two distinct sexes?

The vast majority of plants have both male and female sexual organs, and when two or more plants fertilise each other, all normally produce seeds or spores.

However in most animals the population is divided into males and females, of which only the females bear offspring.

Plants do not have the same kind of opportunity that animals have to find, pursue, and mate with another member of their species, since they are either rooted in one location, or in the case of aquatic plants, just go wherever the water takes them.  Plants cannot really compete for mates or evolve into a more sexually attractive form.  They just cast their spores to the wind.  So sexuality has a much more active role in the animal world.
