　　Passage 1
　　（安徽省桐城六中2010届高三第二次模拟月考）
　　All plant cells are capable of tap water. Even dead ones do to a certain degree. Absorption（吸收）of water by dead cell walls makes wood bee larger. In mon land plants, the living cells of roots tap most of the water. Land plants without roots do exist, however. Those greenish-yellow lichens（苔藓）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（进化）recently and are thus considered higher on the evolutionary scale（进化度）. 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（露水）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 bromeliads growing high above the streets on the insulation（绝缘物）of electric wires. These plants get their water from rain, and the only soil they ever e in contact with is the dust that may blow on their leaves.
