Plant Reproduction Reproduction in seed plants
Gymnosperms Gymnosperm seeds are not enclosed
by a protective fruit
Gymnosperms1. What structure produces pollen?2. How is pollen transferred from the
male to the female cone?
Angiosperms Plants that produce flowers and fruits In your notebooks, list some
angiosperms you’re familiar with.
Angiosperms In gymnosperms, the cone is the
reproductive structure. In angiosperms, the flower is the
reproductive structure.
Angiosperms1. What is the function of flowers?2. What structures make up the male
parts of a flower?3. The female parts?4. What purpose do the color and
shape of the petals serve?
A Bee as a Pollinator On which of the bee’s structures can
you observe pollen?
All seed producing plants can be divided into 2 categories:
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
Pollination Angiosperms and gymnosperms are
wind pollinated but most angiosperms rely on birds, bats, and insects.
Seed Dispersal Seeds are dispersed by:1. Wind2. Water3. Animals
Seed dispersal Animals bury or hide fruits and seeds Animals eat fruits and seeds are not
damaged when they pass through digestive tract
Seed dispersalSeeds inside dry fruits that have tiny hooks attach to animals or clothing
Sketch and label a flower Sketch a flower in your notebook and
label the parts.
Gymnosperm vs. AngiospermWarm-Up
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
Rafflesia “stinking corpse lily” Foul odor attracts pollinators
