Presentation Transcript

  1. Plant Science A Unit of the Michigan State University Extension Master Gardener Curriculum

  2. Plant Science Topics • Plant science • Plant growth and development • Plant propagation

  3. Plant Science Plant Science • Botany • Horticulture • Agronomy • Forestry

  4. Plants - Physiology - Genetics - Taxonomy Cultivated plants Ornamentals Flowers Vegetables Fruit Plant Science Botany Compared to Horticulture

  5. Plant Science Ornamentals -Landscape Horticulture

  6. Plant Science Flowers - Floriculture

  7. Plant Science Vegetables - Olericulture

  8. Plant Science Fruit - Pomology

  9. Plant Science Plant Science • Anatomy - Structure • Physiology - Function • Morphology - Shape

  10. Plant Science What Is a Plant? • Living organism • Contains chlorophyll • Can manufacture its own food • Multicellular with rigid cell walls

  11. Non-Vascular Plants Vascular Plants Plant Science Plant Kingdom

  12. Plant Science Vascular Plants Flowering Angiosperms Non-flowering Gymnosperms “Others”

  13. Plant Science Angiosperms • Monocots • Dicots

  14. Plant Science Cotyledons • Monocots • One • Dicots • Two

  15. Monocots Usually parallel Dicots Usually net-like Plant Science Leaf Venation

  16. Plant Science Flower Parts • Monocots • Usually in threes • Dicots • Usually four or five

  17. Plant Science Vascular System • Monocots • Complex arrangement • Dicots • Arranged in a ring

  18. Plant Science Physiological Differences • Monocots are not killed by broadleaf herbicides • Dicots will be killed by broadleaf herbicides

  19. Plant Science Response to Herbicides

  20. Plant Science Plant Classification • Family - Rosaceae • Genus - Rosa • Specific epithet - hybrida • Cultivar – ‘Nearly Wild’

  21. Plant Science Common Names • Goutweed • Bishop’s Weed • Bishop’s Goutweed • Snow on the Mountain

  22. Plant Science Binomial Nomenclature • Developed by Carl von Linné in 1753 • Two word name for each plant or animal • Genusname followed by a descriptive name or specific epithet • Together the two words identify a species

  23. Plant Science Binomial Nomenclature Aegopodium podagraria ‘Variegatum’

  24. Plant Science Cells Tissues Organs What Makes Up a Plant?

  25. Plant Science Plant Cell Cell wall Plasma membrane Vacuole Chloroplast Cytoplasm Nucleus

  26. Plant Science Cells Tissues Organs

  27. Plant Science Plant Tissues • Meristematic • Dermal • Vascular

  28. Plant Science Meristematic Tissues • Apical meristem • Located at the tip of a shoot or root • Lateral meristem • Formed in stems and roots of many plants • Allows plant to grow in diameter • Vascular cambium is a lateral meristem

  29. Plant Science Dermal Tissue • Epidermis • Cuticle • Stomata • Periderm • Protective covering • Lenticels

  30. Plant Science Lenticels

  31. Plant Science Vascular Tissue • Xylem • Conduct water and minerals within the plant • Phloem • Move food (carbohydrates) produced by photosynthesis to other parts of the plant

  32. Plant Science Cells Tissues Organs

  33. Animals Digestive Circulatory Endocrine Plants Root Shoot Plant Science Organ Systems

  34. Plant Science Plant Organs • Roots • Stems • Buds • Leaves • Reproductive structures

  35. Plant Science Root Functions • Anchorage • Absorption • Storage

  36. Plant Science Root Structure Root Hair Root Cap

  37. Plant Science Root Type Fibrous Tap Tuberous

  38. Plant Science Plant Organs • Roots • Stems • Buds • Leaves • Reproductive structures

  39. Plant Science Stem Function • Supports buds and leaves • Provides structure for vascular system

  40. Plant Science Stem Structure • Xylem • Phloem • Cambium Cambium Xylem Phloem

  41. Plant Science Stem Structure • Nodes • Internodes • Lenticels Node Internode Node

  42. Crowns Tillers and stolens Spurs Tubers Rhizomes Corms Bulbs Plant Science Stem Type
