PollinationsexualWhen pollen is transferred from the anther to the stigma Flowering plants plants don’t have to move mixes DNA need a pollination vector 5. Sexual Reproduction sexualEgg and sperm unite to form a zygote Most animals and some plants results in genetically differences slow

Class Starter Questions 1. Draw a picture of a flower and try to label it’s parts as best you can. 2. Can you Identify which are the female and male parts?

Parts of a Flower 1. Sepals 2. Petals 3. Stamens 4. Pistil pistil

Sepals u Sterile, leaf-like structures. (do not have the capacity to produce gametes) u May be brightly colored. u Function u Protect other flower parts. u Attract pollinators.

Petals u Sterile flower part. u Often brightly colored. u Function u Attract pollinators.

Stamens u Male reproductive flower structure. u Function u Produce pollen (like plant sperm).

Stamen Structure u Anther - pollen producing sac. u Filament - stalk.

Pistil u Female reproductive flower structure. u Function u Produce ovules.

Pistil Structures u Stigma – receives the pollen. u Style – stalk. u Ovary – contains the ovules.

Ovule u An immature seed before fertilization. u The ovules are the female gamete.

Pollen Development u Pollen is the male gamete.

Pollination u The transfer of pollen from the filament to the stigma.

Pollen Vectors u Bees Flies u Butterflies Moths u Birds Beetles u Bats Wind

Fertilization u The union of the ovum and sperm to produce a zygote.

After Fertilization u Zygote (fertilized egg cell)  plant embryo u Ovule  Seed u Ovary  Fruit

Fruit Functions u Protect the seeds. u Aid in seed dispersal.

Seeds u Contain a miniature plant. u Main dispersal mechanism for plants.
