Article: All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take upmost of the water. Land plants without roots do exist, however. Those greenish-yellow lichens you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots. Even among the flowering plants, one finds rootless forms. These flowering plants are "the higher plants" because they evolved recently and are thus considered higher on the evolutionary scale . In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees growing high above the streets on the insulation of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

Article: It would be hard to find a person in America who has never eaten a hamburger, but this popular food was not originally made in America. The original hamburger can be traded back to the Middle Ages, when Russians ate raw meat that was scraped and shredded with a dull knife and formed into patties , It was called Tartar steak. This was the first step in a long series of developments that eventually resulted in hamburger as we know it today. German sailors picked up the raw meat delicacy in their contacts with Russians and brought it back to their home port of Hamburg. But the people there were unused to eating raw meat , so they broiled the outside of the Russian steak; thus the hamburger steak was born. The hamburger steak was brought ot America in the nineteenth century immigrants. Louis Lasssen, a cook in New Haven, Connecticut, modified the hamburger steak by sandwiching it between two pieces of bread. But the true American hamburger came into existence in St. Louis at the Louisiana Purchase Exposition in 1904. A harried cook at the fair quickly slapped broiled beef patties between buns and served them to a demanding crowd, which gulped them down joyously. At first this new food creation was made from scraps of poorer cuts of meat that were not used for anything else, but before scrapes were not enough. The demand for greater quantities of hamburger could only be met by using more and better cuts . Hamburger stands sprang up all over the country, and a side industry of condiments , such as ketchup and relish, grew
