15.2 Control and Coordination in plants
Electrical communication in the Venus Flytrap
inside of lobes has 3 stiff sensory hair
when insect touches these hairs
stimulates an action potential
causes lobes to fold together along midrib
How closure achieved
of the trap is
1 simony hair touched with force
enough
2 Cast channels at base of hair is activated
when channels are open Cast flow in and
generate a receptor potential
3 it 2 sensory hairs are stimulated within a
period of
35 secs or a short period of time
or I hair is stimulated twice in 35 secs
action potentials will travel across the trap and cause it to clos
when trap is open lobes of leaf are convex
U
open
when trap closes lobes become
f
triggered concave
blend downwards closed
occurs as a result of
a release of elastic tension
in cell walls
