Plants and spores

Today I created the plants for eating and the spores which the plants give off for reproduction.  At the moment the plants create a lot of spores that don't do anything but go with the flow of fluid simulator.  When I get collisions done they can be eaten along with plants by the herbivorous species.  Also I have almost finished spores turning into a plant after a time but I need the collisions working to make sure that the plants don't end up growing on top of each other.  Now I am hungry so I am going home.
