The section of the bladderwort and functioning
                                           of the trap: 1- The prey touches the hairs of the
                                           trap, 2- The trap opens immediately and the
                                           prey enters inside, 3 - The gate closes behind
                                           the prey.





               First, the glands activate the extensions attached to them, which start
           pumping the water out. A very important void forms in the plant. At the
           mouth is a trap door that keeps water from coming inside. The hairs on
           this trap are very sensitive to touch. When an insect or organism touches
                                                        these hairs, the trap
                                                        opens     immediately.
                                                        Naturally, this creates a
                                                        strong flow of water
                                                        towards the inside of the
                                                        bladderwort. The trap
                                                        closes behind the prey in
                                                        a flash. Immediately
                                                        after this event, which
                                                        takes place within one
                                                        thousandth of a second,
                                                        the digestive glands start
                                                        releasing     digestive
                                                        secretions. 52
