Wow, I had no idea how many myths about how VFTs move existed. Currently, the exact methoid of triggering is still being investigated, but in other touch sensitive plants, chemical signals are used. However, the actual movement itself is caused by extreamly fast cell divition and elogation in VFTS. In effect, the trap has a very fast growthspurt on the outerwalls causing the leaf to close, when it reopens, the inside cells grow out to straited the trap back out. Eventually the cells become to numerious to efficently outgrow one side and close and that it when we say the plant has a tired trap. VFTs have a trick for this too though, they slowly grow the cells on the innner surfice to eventually push open the trap to capture light [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]
Cool isn't it? Anyways, this also explains the movement discution in the other recent post, but I didn't go in depth their cause I thought it was common knowledge o_O I need to remember stuff like this doesn't come on the grow instructions, lol!
