Title: Plant Reproduction


1
Plant Reproduction
  • Chapter 4

2
What is the difference between Sexual
Reproduction and Asexual Reproduction?
  • Sexual requires an egg and sperm
  • 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?
  • 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)
