The plant-like organisms on this planet are mostly trees and bushes, with only a handful of flowers, but no fungi species. The trees and bushes come in all sorts of forms, both tiny and huge.
While most organisms don't have to fear being completely destroyed when eaten by animals, some have made sure they will survive either way. Some will prevent being eaten by tasting horrible, by growing thorns or by being poisonous. But there are a handful of species who, in a way, need to be eaten. When an animal begins eating these species, they will release the seeds around the eaten area, which are either swept away with the wind or get stuck on the animal to be taken away and thus ensure the species can continue to grow in other areas.
The wonderful diversity is not unique to life on the surface. Life underwater has also given birth to a wide variety of corals and aquatic plants. While corals are in the vast majority, it's the plants that have developed into the most unique and beautiful species on this planet. Their colours are oddly diverse and makes for an amazing spectacle.
