venus fly trap what are the leaves called
Blades (Traps). The trapping part of the Venus fly trap plant is a modified leaf sometimes called a blade.. These trapping leaves are folded in half along something called a petiole, which works as a hinge, giving the trap the ability to open slowly and close quickly.The inside of the leaves are covered with small hairs.enus fly traps have roots that are called rhizomes. These are actually part of the plant's stem that grows horizontally under the ground. Small root hairs grow from the bottom of the rhizome, while shoots sprout up from the upper portion of the rhizome.
