Transcript
Between the field where the flag is planted there are 9+ miles of flower fields that go
all the way to the ocean. The flowers are grown by seed companies. It's a beautiful
place close to Vandenberg AFB. Checkout the dimensions of the flag.
The 2002 Floral Flag is 740 feet long and 390 feet wide and maintains the proper
Flag dimensions as described in Executive Order #10834. This Flag is 6.65 acres and
is the first Floral Flag to be planted with 5 pointed Stars comprised of White
Larkspur. Each Star is 24 feet in diameter; Each Stripe is 30 feet wide. This Flag is
estimated to contain more than 400,000 Larkspur plants with 4-5 flower stems each
for a total of more than 2 million flowers. You can drive by this flag on V Street
south of Ocean Ave. in Lompoc, CA.

CHARACTERISTICS OF PLANTS
1.
2.
3.
4.
Multicellular
Eukaryote
Have cell walls made of cellulose
Carry out photosynthesis using
chlorophyll a & b
5. Most are autotrophs
• A few are parasites (live on living
organisms) or saprobes (live on dead
organisms)
6. Store energy as starch (carbohydrates)
WHAT PLANTS NEED TO SURVIVE:
1.
2.
3.
4.
5.
Sunlight
Water
Minerals
Gas Exchange
Transport of water and nutrients throughout
the plant body
Remember Photosynthesis:
6H2O + 6CO2 → C6H12O6 + 6O2
Water
Carbon Dioxide
Glucose
Oxygen
EVOLUTION OF PLANTS
⦿ Plants
most likely evolved from an
organism like the freshwater multicellular
green algae living today.
⦿ Plants had to overcome “challenges” as
they moved from water to land:
1. Adapt to be able to acquire water
2. Adapt features to transport water
3. Be able to conserve water more
efficiently
EVOLUTION OF PLANTS
4 MAIN PLANT GROUPS:
1.
2.
3.
4.
Bryophytes (Mosses and their
relatives)
Seedless Vascular (Ferns and their
relatives)
Gymnosperms (Cone-bearing plants)
Angiosperms (Flowering plants)
THE 3 MOST IMPORTANT
FEATURES THAT ARE USED TO
CLASSIFY THE PLANTS INTO
THESE 4 GROUPS ARE:
1.
2.
3.
Waterconducting
tissue
(vascular)
Seeds
Flowers
VASCULAR PLANTS VS.
NONVASCULAR PLANTS
VASCULAR PLANTS – Contains
tubelike cells for transport
•Can grow large and farther away from
water source.
•Examples: trees, flowers, & ferns
NONVASCULAR PLANTS – Does not
contain tube-like cells for transport.
•Water and nutrients travel in an out of
cells by diffusion and osmosis.
•Small and grows close to water source.
BRYOPHYTES
BRYOPHYTES - NONVASCULAR PLANTS
require moist environment
•
•
•
Plants draw up water by osmosis only a few
centimeters above the ground.
Low growing plants that are found in
moist, shaded areas.
Includes: Mosses, Hornworts,
and Liverworts
RHIZOIDS – A LONG THIN CELL THAT
ANCHORS MOSS TO THE GROUND
•Found in mosses and absorbs water
and minerals from the soil.
EXAMPLES OF BRYOPHYTES
MOSS
LIVERWORTS
HORNWORTS
LIFE CYCLE OF A MOSS
STEP 1: When a moss spore lands in a moist place, it germinates
and grows into a mass of tangled green filaments called
PROTONEMA.
LIFE CYCLE OF A MOSS
STEP 2: As the PROTONEMA grows, it forms
RHIZOIDS that grow into the ground and
shoots that grow into the air.
STEP 3: These shoots grow into familiar green moss
plants, which are the gametophyte stage
(haploid or gamete-producing plant) of its
life cycle.
USES OF MOSS
Peat – Dead moss that can be burned as fuel or added to soil
to help retain water and increase acidity of the soil.
