Translocate water and minerals to stem 4. Store FoodStems: Stems 1. Translocate water, minerals and food to the leaves 2. Support the leaves and display them to light 3. Store FoodLeaves: Leaves 1. Make food through photosynthesis 2. Provide site of gas exchange 3. Store foodFlowers: Flowers 1. Contain organs for specialized sexual production 2. Produce seeds and fruitDifferent type of Roots: Different type of Roots A. Tap Root Continuation of the primary root Ideal for anchorage Penetration is greater for water Storage area for food made by photosynthesisARE YOU PAYING ATTENTION?: ARE YOU PAYING ATTENTION? THERE JUST MAY BE A QUIZ!!!Different type of Roots: Different type of Roots B. Fibrous Roots Many finely branched secondary roots Shallow roots cover a large area More effective absorption of water and minerals Roots hold the soil to prevent erosionDifferent type of Roots: Different type of Roots C. Aerial roots Clinging air roots Short roots that grow horizontally from the stems Roots that fasten the plant to a support Absorptive air rootsDifferent type of Roots: Different type of Roots Adventitious Roots Develop in places other than nodes Can form on cuttings and rhizomesRoots: Roots Root hairs: Tiny one celled hair like extensions of the epidermal cells located near the tips of the roots where vascular tissues have formed. Increase surface area Absorb water and minerals from soilSpecialized Stems: Specialized Stems A. Corm (gladiolus, crocus) underground Solid, fleshy, scale coveredWAKE UP!!!!!!!!!!!!: WAKE UP!!!!!!!!!!!! DON’T FALL ASLEEP PAY ATTENTION! THIS MEANS YOU!!!Specialized Stems: Specialized Stems B. Bulb (tulips, lillies, onions) Layers of fleshy scales that overlap each other Underground stemSpecialized Stems: Specialized Stems C. Tuber (potato, caladium) Food storage area Short, thick underground stemSpecialized Stems: Specialized Stems D. Crown (African Violets, fern) Closely grouped stems or plantlets Just above ground or just belowSpecialized Stems: Specialized Stems E. Spurs (pear and apple trees) Short sems found on woody plant limbs adapted for increased production of fruitsSpecialized Stems: Specialized Stems F. Rhizomes (iris, lily of the valley) Underground stems that produce roots on the lower surface and extend leaves and flower shoots above the groundSpecialized Stems: Specialized Stems G. Stolon (Strawberry, airplane plant) Stem that grows horizontally above the soil surface Principal Tissues of the Leaf: Principal Tissues of the Leaf Epidermis Cuticle Waxy substance covers the leaves and stems Waterproof layer that keeps water in plantsPrincipal Tissues of the Leaf: Principal Tissues of the Leaf Epidermis (cont) Stomata Openings in the epidermis mainly located on underside of leaves Exchange of gasesPrincipal Tissues of the Leaf: Principal Tissues of the Leaf Epidermis (cont) Guard Cells Two cells located on each side of stomata Open and closes stomataPrincipal Tissues of the Leaf: Principal Tissues of the Leaf Mesophyll layer Palisade mesophyll Primary site of photosynthesis Spongy mesophyll Contains air and chloroplasts Site of photosynthesis and gas exchangePrincipal Tissues of the Leaf: Principal Tissues of the Leaf Veins or vascular bundles In spongy mesophyll Phloem tissues conduct food from photosynthesis to rest of plant Xylem tissues conduct water and minerals up to cells in leaves and stemsParts of the Flower: Parts of the Flower Sepals Outer covering of the flower bud Protects the stamens and pistills when flower is in bud stageParts of the Flower: Parts of the Flower Petals Brightly colored Protects stamen and pistills Attracts pollinating insectsParts of the Flower: Parts of the Flower Stamens Male Reproductive part Anther-produces pollen Filament-supports the antherParts of the Flower: Parts of the Flower Pistil Female reproductive part Ovary Enlarged portion at base of pistill Produces ovules which develop into seeds Stigma Holds the pollen grainsParts of the Flower: Parts of the Flower Style Connects the stigma with ovary Supports the stigma so that it can be pollinatedComplete and Incomplete Flowers: Complete and Incomplete Flowers Complete: have all four main parts Sepals Petals Stamens Pistils You do not have the permission to view this presentation.
