Presentation Transcript

  1. Plant Parts and Their Functions Joel Berry Topic # 2014 A/B

  2. Diversity in the Plant World http://www.uky.edu/Projects/SeedBiology/images/corn.jpg http://entomology.wisc.edu/~cullen/research/Soybean-Aphid_Hayes.jpg http://cropandsoil.oregonstate.edu/crops/seeds/ogscr/sowhwh/head.jpg

  3. Key Focus Points • Structures of a plant • Root • Leaf • Flower • Functions of those structures

  4. Tap Root Systems • CHARACTERISTICS: • 1 Main root • Small roots develop from main root • ex: Carrot http://www.greencastle.k12.in.us/HS/Botany/root_structure_files/slide0014_image028.jpg

  5. Fibrous Root Systems • CHARACTERISTICS: • Numerous slender roots • Shallow root system • Ex: grass http://www.cactus-art.biz/note-book/Dictionary/aaa_Dictionary_pictures/Fibrous_root_system.jpg

  6. Root Functions • Absorb water and nutrients from the soil • Anchor the plant to allow upright growth • Store food that is processed in the leaves Plants and Animals, Biology and Production Lee/Biondo/Hutter/Westrom/Patrick

  7. Root Structure • Root Hairs • Primary Root • Root Cap • Zone of Elongation http://www.cactus-art.biz/note-book/Dictionary/aaa_Dictionary_pictures/Fibrous_root_system.jpg

  8. Root Structures and Functions • Root Hairs: increase water and mineral absorbance by the plant • Primary Root: the initial root that anchors the seedling • Root Cap: protects the root as it pushes through the soil • Zone of Elongation: region of new root growth Plants and Animals, Biology and Production Lee/Biondo/Hutter/Westrom/Patrick

  9. Leaf Structure • Epidermis • Stoma • Guard Cells http://www.bbc.co.uk/scotland/education/bitesize/standard/img/biology/leaf_structure_al.gif

  10. Leaf Structure and Function • Epidermis: skin-like protective layer of cells • Stoma: openings in the leaf that allow exchange of: oxygen, carbon dioxide,& water vapor • Guard Cells: control the opening and closing of the stoma Plants and Animals, Biology and Production Lee/Biondo/Hutter/Westrom/Patrick

  11. Flower Structure • Sepal • Petal • Stamen • Pistil • Ovary http://extension.oregonstate.edu/mg/botany/images/fig19.gif

  12. Flower Structure and Function • Sepal: protects the flower before it opens • Petal: brightly colored to attract pollinators • Stamen: male reproductive part of the flower • Pistil: female reproductive part of the flower • Ovary: contains eggs and is the site of seed development

  13. Conclusion • Quiz hints • Focus on: • Functions of each part of a plant • Be able to label the structure of a plant
