PLANTS EVERYWHERE


Well yes, there are plants everywhere and many flowers too (although not as big as that of picture, a rafflesia, the biggest flower in the world, but it stinks of rotting flesh!) And that, as you must know, is not the same: there are plants without flowers, such as mosses and ferns, and on the other hand, the flowers are a part, not the whole plant, only the reproductive organs of gymnosperms and angiosperms.
Happy Easter and happy spring for all!
