Roots2 Types of Root SystemsTaprootFibrous SystemImage found at: http://www.puc.edu
RootsTaproot SystemPrimary roots grow down from the stem with some secondary roots formingImage found at: http://www.arboretum.fullerton.edu
RootsFibrous Root System
Small lateral roots that spread out just below the soil surfaceImage found at: www.wildmanstevebrill.com
Can you identify these root types?
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 PartsBladeMain body of leafPetioleAttaches blade to stemMidribLarge central veinImage found at: www.yourdictionary.com
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
Parts of the StemNodeAreas where side branches and leaves developInternodeArea between nodesXylemCarries nutrients upPhloemCarries nutrients downPithStores foodImage found at: www.ext.colostate.edu
