Biotechnology Umeshsharma167@gmail.comPowerPoint Presentation: The Four Basic Parts of Plants Leaves Stems Roots FlowersPowerPoint Presentation: Leaves Functions Make food through photosynthesis Site of gas exchange Respiration Photosynthesis Store foodPowerPoint Presentation: Tissues of the Leaf (Epidermis) Cuticle Waxy substance that covers the leaves & stems Waterproof layer that keeps water in plantsPowerPoint Presentation: Tissues of the Leaf (Epidermis) Stomata Openings in the epidermis mainly located on the underside of leaves Exchange of gasesPowerPoint Presentation: Tissues of the Leaf (Epidermis) Guard Cells Two cells located on each side of stomata Open and closes stomataPowerPoint Presentation: Tissues of the Leaf (Mesophyll Layer ) Palisade Mesophyll Primary site of photosynthesis Spongy mesophyll Contains air & chloroplasts Site of photosynthesis and gas exchangePowerPoint Presentation: Tissues of the Leaf Vascular Bundles Called veins In spongy Mesophyll Phloem moves food from leaf to the rest of the plant Xylem moves water & minerals up to leaves from rootsPowerPoint Presentation: Tissues of the LeafPowerPoint Presentation: External Parts of the Leaf Petiole Leaf stalk or part that connects the leaf to the stem. Blade The large, flat part of a leaf. Midrib The large center vein.PowerPoint Presentation: External Parts of the LeafPowerPoint Presentation: Leaf FormsPowerPoint Presentation: Leaf MarginsPowerPoint Presentation: Leaf TipsPowerPoint Presentation: Leaf BasesPowerPoint Presentation: Leaf Arrangements (Simple)PowerPoint Presentation: Leaf Arrangements (Compound)PowerPoint Presentation: Leaf CropsPowerPoint Presentation: Stems Functions Movement of materials Water & minerals from roots to leaves Manufactured food from leaves to roots Support leaves & reproductive structures Food storagePowerPoint Presentation: External Stem Structure Lenticels Breathing pores. Bud Scale Scars Show where terminal buds have been located. Leaf Scars Show where leaves were attached.PowerPoint Presentation: External Stem Structure Terminal Bud Bud on the end of the stem. Axillary Lateral Bud Bud on the side of the stem.PowerPoint Presentation: External Stem StructurePowerPoint Presentation: Internal Stem Structure Xylem The tissue that transports water & nutrients up from roots to stems & leaves. Phloem Tissue that transports food down from leaves to roots. Cambium Thin, green, actively growing tissue located between bark & wood and produces all new stems cells.PowerPoint Presentation: Internal Stem Structure Bark Old, inactive phloem. Heartwood Old, inactive xylem. Sapwood New, active xylem.PowerPoint Presentation: Internal Stem Structure (Monocots) Vascular bundles contain both xylem & phloem. Examples: Grasses CornPowerPoint Presentation: Monocot Stems (Vascular Bundle)PowerPoint Presentation: Internal Stem Structure (Dicots) Plant stems have xylem & phloem separated by the cambium. Example: TreesPowerPoint Presentation: Internal Stem Structure (Dicots)PowerPoint Presentation: Specialized Types of Stems Corm Underground Solid, fleshy, scale covered Examples Gladiolus CrocusPowerPoint Presentation: Specialized Types of Stems Bulb Layers of fleshy scales that overlap each other Underground stem Examples Tulips Lilies OnionsPowerPoint Presentation: Specialized Types of Stems Tubers Food Storage Area Short, thick underground stem Examples Potato CaladiumPowerPoint Presentation: Specialized Types of Stems Crown Closely grouped stems or plantlets Just above or below ground Examples African violet FernsPowerPoint Presentation: Specialized Types of Stems Spurs Short stems found on woody limbs adapted for increased fruit production Examples Apple PearPowerPoint Presentation: Specialized Types of Stems Rhizomes Underground stems that produce roots on the lower surface and extend leaves and flower shoots above ground Examples Iris Lily of the ValleyPowerPoint Presentation: Specialized Types of Stems Stolens Stem that grows horizontally above the soil surface Examples Strawberries Airplane PlantPowerPoint Presentation: Stem CropsPowerPoint Presentation: Roots Functions : Anchor the plant Absorb water & minerals Store food Propagate or reproduce some plantsPowerPoint Presentation: Different Types of Roots Tap Root One main root, no nodes Continuation of the primary root Ideal for anchorage Penetration is greater for water Storage area for foodPowerPoint Presentation: Different Types of Roots Fibrous Root Many finely branched secondary roots Shallow roots cover a large area More efficient absorption of water & minerals Roots hold the soil to prevent erosionPowerPoint Presentation: Different Types of Roots Aerial Roots Clinging air roots Short roots that grow horizontally from the stems Roots that fasten the plant to a support Absorptive air roots Absorb moisture from the airPowerPoint Presentation: Different Types of Roots Adventitious Roots Develop in places other than nodes Form on cuttings & rhizomesPowerPoint Presentation: External Parts of Roots Root Cap Indicates growth of new cells.PowerPoint Presentation: External Parts of Roots Root Hairs Tiny one celled hair-like extensions of the epidermal cells located near the tips of roots. Increase surface area. Absorb water & minerals.PowerPoint Presentation: Internal Parts of Roots Much like those of stems with phloem, cambium and xylem layers. Phloem The outer layer. Carries food down the plant. Xylem The inner layer. Carries water & minerals up to the stem.PowerPoint Presentation: Root Crops You do not have the permission to view this presentation.
