The time required for a typical atom in the oceanic plate to complete the plate tectonic cycle is about in excess of two hundred fifty million years in which this is required for it to developed and to be fully complete for it to fully finish the plate tectonic cycle.
The answer is; NO
This is because the leaf would not have tiny oxygen bubbles spread across its base (because the base is where most stomata are) that would help it float on the water. The reason is that the oxygen produced in the process of photosynthesis would be consumed in respiration because the rates of the two biochemical processes are the same.

The vinegaroon has became very similar in appearance to the scorpions, by having similar body, similar proportions to certain species, having a whip tail. The whip tail though is not a mimic for the scorpion's pincher claws, but instead, it is a mimic of the scorpion's stinger. This adaptation of the vinegaroon has the purpose to fend of the predators by making them think that it is actually a scorpion and that they will get a nasty poisonous sting. This type of adaptations by mimicking certain traits of more dangerous species can be found in lot of animals from all shapes and sizes.
