2. Angiosperm A plant that produces seeds that are enclosed in fruit
Greek word that means seed in a vessel
Two
characteristics of an angiosperm:
Flower
Fruit

3. Flower Vocabulary Petals – colorful structure when flower opens
Sepals – leaf like structures that enclose a bud

4. Flower Vocabulary Stamens – male reproductive parts
Filament – thin stalk
Anther – produces pollen – knob at top of filament

5. Flower Vocabulary Pistils – found in center of flower
Stigma – sticky tip of pistil
Style – slender tube that connects the stigma to the ovary (hollow base of the flower where ovules are

6. Angiosperm Flower

7. Reproduction of an Angiosperm
Pollen falls on stigma
Sperm and egg cell join together in flower’s ovule
Zygote develops into the embryo part of the seed

8. Seed Dispersal As seed develops, the ovary changes into a fruit
a ripened ovary and other structures that enclose one or more seeds

9. Types of Angiosperms
Divided into 2 major groups
Monocots
Dicots

10. Monocot Have one seed leaf
Flowers usually have either three petals or a multiple of three petals
Long slender leaves with veins that run parallel to each other
Bundles of vascular tissue is scattered throughout stem

11. Dicots Produce seeds with two leaves
Flowers have 4 or 5 leaves or multiples of these
Leaves are wide with veins that branch off from one another
Bundles of vascular tissue bundled together
