Transcript Plant Reproduction

 Reproduction
in seed plants
 Gymnosperm
seeds are not enclosed by
a protective fruit

What structure produces pollen?
How is pollen transferred from the male
to the female cone?
 Plants
that produce flowers and fruits
 In your notebooks, list some angiosperms
you’re familiar with.
 In
gymnosperms, the cone is the
reproductive structure.
 In angiosperms, the flower is the
reproductive structure.

What is the function of flowers?
What structures make up the male parts
of a flower?
The female parts?
What purpose do the color and shape
of the petals serve?
 On
which of the bee’s structures can you
observe pollen?
GYMNOSPERM






Oldest type of seed plant
Seeds are NOT enclosed in
a protective coating
Needle-like leaves
Produce cones for
reproduction
Deep roots
Mostly trees
ANGIOSPERM




Most common type of seed
plant
Seeds are protected inside
a fruit
Produce flowers for
reproduction
Live almost everywhere on
Earth
 Angiosperms
and gymnosperms are
wind pollinated but most angiosperms
rely on birds, bats, and insects.
 Seeds

are dispersed by:
Wind
Water
Animals
 Animals
bury or hide fruits and seeds
 Animals eat fruits and seeds are not
damaged when they pass through
digestive tract
Seeds inside dry fruits that have tiny
hooks attach to animals or clothing
 Sketch
a flower in your notebook and
label the parts.
Create a Venn diagram in your notebook. Label the sections Angiosperm,
Gymnosperm and Both. Classify each characteristic in the correct category.

Seeds protected inside a fruit
Reproduces using seeds
Needle-like leaves
Produces cones for reproduction
Most common type of seed plant
Produces flowers for reproduction
Oldest type of seed plant
Contains leaves, stems, and roots
"naked seed"
“seeds in a little case” angio (little case)
Redwood and pine trees
Apple trees and roses
Uses photosynthesis to make food
 “stinking
corpse lily”
 Foul odor attracts pollinators
