Technically, all plants are very much alive. I believe you were referring to the Venus Fly Trap’s ability for movement, though? Venus Fly Traps
are part of a very small group of plants that are capable of rapid movement; if the plant is healthy and the environmental conditions are good, they
can close their traps in .1 seconds.
The plant itself does not contemplate the right time to ‘strike’ and close its traps, they are operated by a trigger mechanism. There are small
hairs on the surface of the traps, and whenever something (spiders, flies, ext.) triggers one or more of those hairs twice in succession, the trap
closes. The trigger is a safeguard to better preserve its energy, and not use it up on false starts.
I believe all plants are very capable of movement, though oftentimes it is a very slow process. I don’t think that their movements are
premeditated; more that they happen to compensate for changes in their surroundings to better capture sunlight or nutrients. I personally have a
plant that I have to turn every few hours; it tries to shove its leaves under the blinds and will end up hurting its leaves if I don’t watch it.
(And I do realize this is because it needs light, I just usually forget to open the blinds when I get up, and this is a good reminder.
One last comment, on the subject of their movements being premeditated: I think this could also be compared to other creatures that do not possess a
brain, and run on instinct alone. Forgive me if this assessment is wrong, but I think it might make a good comparison.
