Cards in this set: Term tree Definition A tall plant with a single woody stem. Term perennial Definition A plant that lives for many years. Term annual Definition A plant that lives for one year. Term biennial Definition A plant that lives for two years. Term California redwood Definition The tallest living trees in the World. Some California redwoods are over 300 feet tall. Term dendrologist Definition A scientist who studies trees. Term bristlecone pine Definition Probably the oldest living things on earth. Some of these trees are 4000-5000 years old. Term banyan tree Definition The banyan tree spreads outward by sending thick roots down from its branches to the ground. There is a banyan tree in India with over 1700 root columns, which covers an area of three acres, and forms a forest all by itself. Term candlenut tree Definition The state tree of Hawaii. The candlenut tree has unusual nuts containing an oil that burns very well. Before electricity came to the islands, Hawaiians strung dried canclenuts together on the rib of a coconut leaf. Then the children set them on fire one at a time, each nut burning for two or three minutes to provide light in the evening. Term baobab tree Definition The baobab tree of the African grasslands seems almost as wide as it is tall. It has a huge trunk that stores water to last throughout the dry season. An old baobab tree in Australia had a hollowed-out trunk so large that for a while it served as the town jail. Term bud Definition The massive trunk of a tree is simply a very large stem. The stem grows lengthwise only at its tip, where a small knobby structure called a bud produces new growth. As the stem grows longer, small buds appear on the sides of the stem. These buds grow outward from the stem and become branches. Each branch is tipped by a bud and is able to produce new side buds as well. Term girdling Definition Removing a ring of bark from the trunk of a tree. This causes the tree to die Term bark Definition The bark of a tree keeps the wood from drying out, protects the tree from the attacks of parasitic animals or plants and protects from the invasion of disease. The inner layers of a tree's bark contain the pipelines that carry food from the leaves to the roots. Term annual growth ring Definition In spring, when the tree begins to grow rapidly after the winter, the tree forms large cells to carry great quantities of water and food through the stem. This area of rapid growth appears as a light-colored band of wood. Then, in the summer, the tree grows more slowly forming smaller cells. The area of slower growth appears as a dark-colored band of wood. These light and dark bands make up the annual growth rings of the tree. Each annual growth ring is made of an inner band of light spring wood and an outer band of dark summer wood. Together the two bands are one year's growth. Term David Livingstone Definition 1813-1873 Livingstone was the first one to connect mosquitoes with malaria, and he noted the outbreak of the disease with the onset of the rains each year. He used quinine, from the bark of the cinchona tree, to treat malaria. Term uses of trees Definition Spices/flavorings: Cinnamon is made from the bark of a tree. Nutmeg, from the seeds of the nutmeg tree. Cola, from the nuts of the African Kola tree. Fiber from the seed of the kapok tree is used for stuffing pillows, mattresses, cushions, and life preservers.   Some rubbing ointments and throat lozenges contain oil from the eucalyptus tree.   Turpentine is a solvent used to thin or mix paint. Rosin, dried trupentine is used by musicians on the bows of their stringged instruments to create better contact with the strings. Both turpentine and rosin come from the pine tree.   Leather is made from animal hide that is treated with chemical preservatives. Until the 20th century, most leater was preserved using chemicals called tannins, which come from the bark and wood of trees such as oaks and hemlocks. Some leather is still preserved this way.   Quinine is a medicine taken from the bark of the South American cinchona tree, and is used to treat malaria. Term cambium layer Definition If you were to pull away the bark of a tree you would see a sticky, slimy film, which is the cambium layer, the part of the tree where growth takes place.
