  • Unit: Plant Growth & DevelopmentAdvanced Plant SciencesMr. Dieckhoff

  • 1. ID the parts of a plant cellChloroplast holds chlorophyllPlasma Membrane Controls entrance & exitsCell Wall 3 layersCytoplasm Liquid in cellVacuole Store waterMitochondrion RespirationNucleus - Genetics

  • **Four elements of the cell structure:

    A. Cell wall B. Plasma membrane C. Cytoplasma D. Nucleus

  • Cell Wall Structure

  • Too little water in vacuole..

  • Tobacco flower losing pigment because lack of mitochondria proteins

  • 2. What are 2 function of PM?Control entrance & exit into and out of cell

    Relays environmental information about condition

  • 3. What are 3 organellesMitochondria Control Chemical Reactions, site of respiration

    Plastids Contain Chloroplasts; contain chromoplasts (red, yellow, brown pigments)

    Vacuoles store water, dissolve minerals

  • 4. What are 3 func. of nucleus..Control Physiological Characteristics

    Control Appearance of Plant

    Passes Characteristics to Offspring

  • 5. What are 2 types tissue.Meristem


  • 6. What are differencesMeristem actively divides to form new growth where permanent does not actively divide

  • 7. What are 3 types meristems..Apical plant length

    Cambium plant diameter

    Intercalary Zone stem height

  • **Cambium MeristemView Video

  • Intercalary Zone Meristem

  • 8. What two types permanentEpidermis outside covering

    Vascular System transportation system of plantXylem - UpPhloem - Down

  • **Five basic parts of a plant:A. Seeds B. Roots C. Stems D. Leaves E. Flowers

  • 9. What are three parts monoSeed Coat Protect embryoEmbryo Miniature plantEndosperm - Nourishment

  • 10. **Which is found only monoEndosperm

  • 11. What are 4 parts embryo?Cotyledon




  • 12. **What another term seed leafCotyledon

  • 13. What type of Plant.Has one leaf Monocot

    Has two leaves - Dicot

  • **Stems.

  • Stolon

  • **CrownThick, compressed stem whose leaves and flower buds grow just above ground

    Example in CCC Greenhouse: fern

  • Rhizome

  • 14. **What are 3 func. Roots.Synthesize hormones for plant growth

    Store carbohydrates

    Provide aerial support

    Anchor plant

    Absorb Water and Nutrients

  • Application of Rooting Hormone

  • Dont cut alfalfa in October

  • Wait Until November

  • Or Next Year will Look Like.

  • 15. What are 5 types roots.Taproot





  • Adventitious Roots

  • Tap Root

  • Aerial Roots

  • Aquatic Roots

  • 16. What is pith?Parenchyma cells

  • 17. What is hyposophylls?Floral bracts protect buds during developmentDogwood

  • 18. ID interior parts of leaf.PhloemXylemCuticleUpper epidermisChloroplastLower epidermisCuticleStomataGuard CellSpongy mesophyllPalisade mesophyllView Video

  • **The 3 structures of a leaf:

    A. Epidermis B. Mesophyll layer C. Vascular bundles

  • View Guard Cells & Stomata of Wandering Jew

  • 19. What are 2 func. Leaves?Manufacture food through photosynthesis

    Protect vegetative and floral buds

  • 20. What do not have stomata?Submerged plants (aquatic)

  • 21. What are char. xeromorphicThick-walled epidermis covered with waxy cuticle (holds water in stems)

  • 22. What type modified leaf.Sac

  • 23. What is corolla.Petals protect stamen and pistil in bud stage; attract pollinating insects

  • 24. Gynoecium refers toFemale reproductive parts

  • 25. What do head, spike, umbelTypes of inflorescence flowers

  • 26. What are 3 char perfectContain male and female parts

    All four parts of flower are present

    Usually self-pollinating

  • **KNOW

  • **Monoecious (different places) vs. Dioecious (same place)

  • Cross Pollinating

  • Self Pollinating
