The Venus Flytrap is a fascinating plant. Have you ever wondered how the plant 'knows' when to shut?
On the leaves that make the trap, there are short stiff hairs called "trigger hairs". If two or more of these hairs are touched in a short period of time, the jaws of the trap snap shut!
Now how can a plant with no muscles or tendons move so quickly?
Nobody knows! Scientists have some ideas, but do not completely understand how this amazing plant does it!
