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. Aerial photo courtesy of Bill Morson Soldiers' Prayer 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.
