Flowering Plants

  • Seed plants

  • Ovules are enclosed in an ovary

  • Ovary  fruit around seeds

Flowering plants

  • Pollination http://www.lucnix.be

  • Pollen germination

  • Pollen tube growth

  • Double fertilization


Angiosperm seeds
Angiosperm Seeds http://www.lucnix.be

  • Zygote  Embryo

  • Triploid cell  Endosperm (food supply)

  • Integuments  Seed coat


Corn seeds

Question: Where is the endosperm?


Flowering plants

Cotyledon stays within kernel http://www.lucnix.be nutrients from endosperm to seedling
