Cards in this set: Term flowering plant families Definition composite pea rose lily grass Term composite Definition The largest family of flowers. It includes many wildflowers, such as daisies, thistles, goldenrods, and dandelions.   Composite flowers are actually made up of many flowers.   Some foods that come from composite plants are lettuce, artichokes, and sunflower seeds. Term ray flowers Definition Petallike flowers that may be part of composite flowers, either in combination with disk flowers or alone. Term disk flowers Definition Tiny flowers that may be part of composite flowers, either in combination with ray flowers or alone. Term peas Definition The pea family includes garden peas, beans, peanuts, alfalfa, wisterias, redbuds, and kudzu. You can identify plants in the pea family by their pods, as well as by their flowers. Flowers of plants in the pea family have one large petal that spreads out like a fan at the top of the blossom. Two smaller side petals, called wings, almost seem to flutter around two bottom petals that join together to form a pouch. The pouch surrounds and encloses the stamens and the pistil. In order to reach the nectar at the base of the flower, an insect must crawl through the small space within the pouch. Term legume Definition Members of the pea family are called legumes because their fruits grow in the shape of a pod or legume. Legumes give the soil more nutrients than they use. These extra nutrients are produced by bacteria, living on the roots of the legumes, that take nitrogen from the air and change it into nutrients that plants can use. Term pod Definition The fruit of members of the pea family grow in pods. Some pods are tiny, like that of clover, while others are large, like the yard long bean, which can be up to three-feet long. Term roses Definition All plants in the rose family have blossoms with five petals or with multiples of five. Members of the rose family include apples, peaches, blackberies, raspberries, strawberries, plums, and cherries. Many plants in the rose family are hybrids. Term lilies Definition Members of the lily family have blossoms with petals in multiples of three. Some members of the lily family are tulips, hyacinths, day lilies, trilliums, tiger lilies, Easter lilies, and lilies of the valley. Some members of the lily family do not have bulbs, but they still have thick leaves that are used as food storehouses. Among these plants are the cactuslike aloes and yuccas found in desert climates. Term bulb Definition Lilies grow from bulbs, storehouses made with layers of thick, fleshy leaves that surround a very short stem. Bulbs store food during the growing season so that it can continue to live after the stem, leaves, and flowers have died. At the beginning of the next growing season, the bulb sends out a new shoot, which becomes the stem, leaves, and flowers of the new plant. Term grasses Definition The most important family of food-producing plants. One third of the earth's land is covered by grasses. Many of these grasses are cultivated and harvested to provide food. Others are cultivated to cover, beautify, and protect the land. Term cereal grasses Definition Cereal grasses, such as wheat, barley, oats, rice, and corn are harvested for the nutrients in their seeds. Term turf grasses Definition These are the grasses used for beauty and to protect from erosion. Some common turf grasses are Kentucky bluegrass, bentgrass, Bahia grass, Bermuda grass, and centipede grass. Crab grass and quack grass are unpopular, because once established in a lawn they tend to overrun the more beautiful turf grasses planted by man. Term woody grasses Definition Bamboo and sugar cane are woody grasses. Bamboo is the largest grass in the world, it can reach over 100 feet in length, and one foot at its base. Term dicot Definition Biologists divide flowering plants into two main groups: monocots and dicots, based on the number of cotyledons in their seeds. Dicots have seeds with two cotyledons. Their leaves are usually broad and flat, with veins that branch out from the central midrib. Their flower petals come in multiples of four or five. Dicots usually have taproots. Term monocot Definition The seeds of monocots only have one cotyledon. Their leaves usually have parallel veins, and their flower petals come in multiples of three. Monocots usually have fibrous roots. Term Joshua tree Definition One of the largest members of the lily family, it is a form of yucca that grows in Arizona and Utah. Term kokerboom Definition A large, treelike lily which lives in South Africa and may grow to a height of 30 feet. Baboons often climb to the top of the kokerboom to drink the sweet nectar from its flowers. Term John Ray Definition John Ray was a Puritan botanist and naturalist. He lived during the 1600s, and traveled all over the British Isles and European Continent collecting specimens, making observations, and taking notes for a book on natural history. His work on classifying plants and animals was expanded by the Swedish botanist Carolus Linnaeus.
