group 3 seed producing vascular plants
Group 3: Seed producing, Vascular Plants

Type 2: Angiosperms (flowering plants)

Flower = reproductive structure

Attract animals to help spread pollen

Forms fruit to protect and spread seeds

Seeds

Grow inside the fruit

Inside the seed

1. Embryo

2. Food supply

seed dispersal
Seed Dispersal
  • Fruit brightly colored
    • Attracts animals
  • Seeds pass through animals digestive system
  • Seeds pooped in a new area to grow

Fruit seeds in fox poop

angiosperm groups
Angiosperm Groups
  • 2 groups: Based on seed type
  • Cotyledon: embryonic leaf
  • Two Categories:
    • Monocots: embryo with 1 seed leaf
    • Dicots: embryo with 2 seed leaves
monocots vs dicots

angiosperm life spans
Angiosperm Life Spans
  • Three Life Span Types:
  • 1) Annuals
    • Seed grows…
    • Produce flowers & seeds…
    • Die
  • 2) Biennials
    • 1st year:
      • Seed grows and stores food
    • 2nd year:
      • grows more…
      • makes flowers & seeds…
      • dies
  • 3) Perennials
    • Live for more than 2 years
    • May take decades to grow fruit
flowers
Flowers

petals

sepals

  • Reproductive structure of angiosperms
  • Sepals
    • outer ring of leaves
    • protection
  • Petals
    • Inner ring of leaves
    • Brightly colored to attract pollinators
  • Male and female organs found inside
slide19
Flowers
  • Male Stamen
    • Anther: produces pollen
  • Female Carpel/Pistil
    • Inner most part
    • Ovary: within the base
      • Contains eggs
      • Grows into fruit when fertilized
    • Stigma: sticky tip, collects pollen
angiosperm life cycle
Angiosperm Life Cycle

1) Pollen sticks to animal or released into wind

Here is an apple tree….lets zoom into an individual flower.

2) Insect flies away covered in pollen

  • What is the reproductive structure of angiosperms called?
  • What structure protects the seeds of angiosperms?
  • Why are flowers and fruits often brightly colored?
  • Be able to identify the parts of a flower diagram.
  • Which flower part produces pollen?
  • Which flower part will pollen land upon?
  • Which flowers only live for 2 years and then die?
  • Practice the monocot/dicot sample questions.
