Anther The pollen-producing tip of the stamen in a flower Binomial nomenclature The use of genus and species names to identify individual types of plants Brainpower Read More Blade The broad portion of a leaf that contains the veins Calyx The set of leaves, or sepals, at the base of flower's petals Cambium The part of the vascular bundle that surrounds the xylem and phloem and is the site of active plant growth. Also called the meristem. Carpel The ovary of a flower, which contains the ovules that, when fertilized, become seeds. Chlorophyll The green pigment in leaves that carries out photosynthesis Complete flower A flower that contains both male and female reproductive structures. Corolla All of the petals of a flower, collectively. Domain A category higher than "kingdom" in a revision of Linnaeus's taxonomy; added when the model was revised in the 1960s based on molecular research. Family A taxonomy category that has one main characteristic linking plants together; one step higher than genus. Filament The stalk of the stamen that carries the anther. Floret The individual flowers in an inflorescence. Genus A category in Carl Linnaeus's taxonomy; similar to human last names Incomplete flowers A flower that is missing one or more of the male or female reproductive structures needed for self-pollination. Inflorescence The characteristic development and arrangement of flowers on a stem. Internode The area between nodes on a plant stem. Kingdom Highest category in Carl Linnaeus's original taxonomy. Leaf base The point at which a leaf attaches to a stem. Margin The edges of a leaf blade. Meristem The part of the vascular bundle that surrounds the xylem and phloem and is the site of active plant growth. Also called the cambium. Node Area of growth along a stem, where new leaves or flowers are produced. Pedicel The stalk of a flower. Petal The modified leaves that surround the reproductive parts of a flower; often have bright colors or distinct scents to attract pollinators. Petiole The structure that connects a leaf base to the stem of the plant. Phloem Vessels in a plant that conduct food (carbohydrates) throughout the plant. Photosynthesis The process by which green plants transform light energy into chemical energy for food. Pistil The female reproductive organ, consisting of the carpel, stigma, and style. Plant anatomy The internal structure of plants. Plant morphology Study of physical form and external structure of plant material. Plant physiology The functions of the various parts of a plant. Propagated Reproduce; make new plants. Receptacle The part of a flower that attaches to the pedicel and forms the basis for the flower. Rhizome A stem that grows horizontally underground; nodes on the rhizomes can produce new roots and form new plants. Root hair The fine, hair-like projections on the roots through which water and minerals are absorbed from the soil. Rooting hormone powder A plant growth substance containing indoleacetic acid which had been identified as the same chemical as auxin which caused curvature in roots and shoots. The exposed surface of a cutting is dipped into rooting powder and placed into a pot containing moist compost or soil. It helps create a denser root system providing the plant with a better chance of survival. Sepal A modified leaf at the base of a flower. Species A category in Carl Linnaeus's taxonomy that identifies individual types of plants; similar to a human first name. Stamen The male reproductive organ; consists of a filament with an anther at its tip. Stigma The female part of a flower that collects pollen to fertilize the ovules. Stipules Leaf-like structures at each side of the leaf base that help protect the leaf bud. Stomata The pores on the underside of leaves, through which water evaporates through transpiration. Style A tube in the pistil through which pollen passes to reach the carpel. Taxonomy The science of classification of all organisms, both living and extinct. Transpiration The process by which water is transported from the roots of a plant to all parts of the plant and then evaporates from the leaves. Vascular bundle The xylem
