• Someday, many of you will own a home.

You will actually care about plants in your
yard.

gardening skills later.

 New Area of Focus: Plant Life Cycles.

 Annuals: Seed germinates, grows, and
produces new seed, before dying.

 Annuals: Seed germinates, grows, and
produces new seed, before dying.
“I need to plant
new flowers
here every
year.”
“Sometimes old
seeds will
grow.”

 Biennials: Plant lives through first winter
and produces seed before dying.

• Raspberries are biennials.

 Perennials: Plants that live for many years
producing seeds each year.

 Deciduous: Plants and shrubs that lose
leaves in fall and grow them back in spring.

• Broadleaf deciduous leaves wouldn’t
survive the winter.

survive the winter.
– The cold temperatures would freeze the water
inside the leaf.

survive the winter.
– The cold temperatures would freeze the water
inside the leaf.
– Ice attaching to the leaves would snap the
branches.

• Picture of what happens to tree when early
snow / ice storm occurs before leaves have
fallen.

• Evergreens: Needles can survive
winter, trees constantly grow and drop
needles.

• Evergreens: Needles can survive
winter, trees constantly grow and drop
needles.
– Needles can survive cold (sap antifreeze).

 Seed Plant Life Cycles.
 -

 All plants undergo sexual reproduction (two
partners). When the sperm and egg come
together you get a zygote / baby plant.

 Gymnosperm: Non-flowering, seeds usually
arranged on a cone.

“This is one
big cone, It
must be one
of the largest
ever!”

“I agree.”
“Why would
you ever
need a cone
that big.”

“I could sure
go for a
sno-cone.”

Look at the
size of this
cone.

 Angiosperm: Flowering, covered
seed, produce seeds enclosed in a fruit
/ovary.

• Which plant is an angiosperm, and which is a
gymnosperm?

• Both Gymnosperms and Angiosperms
release pollen.

“I hate Pollen, It
gives me wicked
allergies.”

• Picture of pollen under an electron
microscope.

• The male cone of a white pine releasing
pollen.

• Female cone of white pine that receives
the male pollen.

• The seeds of white pine tree that have fallen
out the cone.

• The seeds of white pine tree that have fallen
out the cone.

 Flower: The reproductive organ of a plant
that makes the seed.
