 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.
