Root FunctionsAbsorption of water and nutrientsperformed by root hairsTransportation of water and nutrients to stemAnchor plant to maintain stabilityStore food and water

Roots have 4 primary functions

Parts of the RootEpidermisOutermost layer of cells, like the skin of the rootCortexTissue inside epidermis that stores starch and other substances for the growth of the root

Parts of the RootRoot CapProvides protection for the root tipRoot HairsSite of absorptionVascular TissueWithin cortex, contains cells that transport water, nutrients, and minerals to all parts of the plantImage found at: www.cactus-art.bizImage found at: www.bio.psu.edu

Important Functions of LeavesPhotosynthesisProcess that plants use to produce their food6CO2 + 6H2O C6H12O6 + 6O2TranspirationLoss of water and exchange of carbon dioxide

Leaf PartsApexTip of leafBaseAttaches to petiole if petiole is absent, attaches directly to stemMarginEdge of leafEpidermisSkin of leaf - responsible for gas exchangeStomataOutside layer of leaf opening in epidermis where gas and water exchangeMesophyllMiddle layer of leaf where photosynthesis occurs

Functions of the StemTransport water and nutrients from roots to leavesSupports leaves, fruit, and flowersFood storageImage found at: www.karencarr.com
