(a)Plants have two transport systems to move food, water and mineralsthrough their roots, stems and leaves. These systems use continuous tubes called xylem and phloem, and together they are known as vascular bundles.
Oxygen and carbon dioxide are transported through tiny holes (pores) on the surface of leaves and stems through a network of air spaces within the plant to and from all living cells.
(b)Venus' Flytraps gather nutrients from gases in the air and nutrients in the soil. However, they live in poor soil and are healthier if they get nutrients from insects. Carnivorous plants live all over the world but the Venus Flytrap is native to select boggy areas in North and South Carolina. Because of people's fascination with these plants, they collected many of them and they became endangered. Venus' Flytraps today are grown in greenhouses.
The leaves of Venus' Flytrap open wide and on them are short, stiff hairs called trigger or sensitive hairs. When anything touches these hairs enough to bend them, the two lobes of the leaves snap shut trapping whatever is inside. The trap will shut in less than a second. The trap doesn't close all of the way at first. It is thought that it stays open for a few seconds in order to allow very small insects to escape because they wouldn't provide enough food. If the object isn't food, e.g., a stone, or a nut, the trap will reopen in about twelve hours and 'spit' it out.
