  1. Plant Reproduction

  2. What is the difference between Sexual Reproduction and Asexual Reproduction? • Sexual requires an ovule and pollen • Asexual is vegetative

  3. What are the Female parts of the flower? • Pistil: Stigma, Style, Ovary • Pollen lands on Stigma, travels down style to ovary

  4. What is a Perfect Flower? • Perfect Flower is the same as a complete flower • has Stamen & Pistil on same flower • only one part = imperfect

  5. What is the difference between a Monoecious and Deoecious plant? • Monoecious: male & female flowers on same plant • Dioecious: male & female flowers on different plants

  6. What are the other parts of the flower? • Calyx: all the sepals • Corolla: all the petals

  7. What is a Complete Flower? • A flower that has all four major flower parts: Pistil, Stamen, Calyx, Corolla

  8. What type of flower does the grass plant have? • has calyx, corolla, pistil, stamen • any missing parts = imcomplete • perfect & incomplete

  9. What is a Floret? • basic flower unit

  10. What is a Spikelet? • a group of florets

  11. What are the types of Inflorescenses? • Panicle Inflorescence: (oats, some grasses) branched structure at tip of stem

  12. What are the types of Inflorescenses? • Spike Inflorescence: (wheat, barley) spikelets attached directly to stem.

  13. What are the types of Inflorescenses? • Raceme Inflorescence: (mustard, rapeseed) single flowers attached to stalk or stem.

  14. What are the types of Inflorescenses? • Head Inflorescence: (sunflower) enlarged stem = receptacle

  15. What is a Fruit? • An Apple or Tomato is considered a fruit. A Fruit is a mature ovary. • Fruits can be fleshy (tomato) or dry (wheat)

  16. What is Pollination? • process of transferring pollen grains from the anther to the stigma • plants can be self-pollinated (male & female flowers on same plant) or cross-pollinated (different plants)

  17. What is Fertilization? • when sperm is united with an egg • pollen lands on stigma, germinates, and grows down style to the ovary where sperm fertilizes the egg (pollen tube) • there are actually two fertilizations. Second sperm fertilizes second egg to form the endosperm (food for the seed)
