17 All plants… Eukaryotic & multicellular Are producers – an organism that makes its own food by using an outside energy source (the sun)Have cell walls (organelle only in plants)Have chloroplasts (organelle only in plants)
18 What is a cell wall? Provides support and protection Make of cellulose and ligninAnimals have skeletons to hold them up, plants do not. No matter how tall a plant gets, the cell wall help them hold their shape. Like taking a water balloon and putting it in a cardboard box.
19 What is a chloroplast?Organelle that converts light energy to chemical energy through a process called photosynthesis (we’ll talk about that later)
20 How can plants be classified? Lets create a classification map (tree map)Have students create a classification map in their notes as discuss various types of plants.
33 plants non-vascular vascular Seedless Seed Seedless Angiosperms Does not contain vascular tissueContains specialized tubes that transport water & nutrientsSeedlessReproduces by spores (needs water)No flowersNo roots (have rhizoids)No cuticleSmall in sizeExamples: liverworts, mosses, hornworts, bryophytesSeedSeedlessLarger than nonvascular seedless plantsExamples include: ferns, clubmoss and horsetailsAngiospermsGymnospermsCone-baring seedsExample – pine, cedar, spruce
34 Gymnosperm PlantsPine TreeCedar TreeSpruce Tree
35 Gymnosperms Seeds produced in a cone Group includes oldest plant and tallest plant.Bristlecone Pine - Know to live for over 5,000 years.Coast Redwood - Forest trees grow over 379 feet tall

37 Apple Tree SunflowerLady Slipper OrchidPumpkins
38 Angiosperms Grow in a variety of habitats Most food eaten by humans comes from angiosperms or animals that eat angiosperms.Other items such as clothing, medicine, building materials.Flowering plants
39 Types of Angiosperms Monocots Dicots Narrow leaves with parallel veins.Leaves with branched veinsFlowers with parts in multiples of threesFlowers with parts in multiples of four or fiveStems – vascular tissue in bundles scattered throughout the stemStems – vascular tissue in bundles in ringsSeeds – one cotyledonSeeds – two cotyledons

49 Video – “Life” by BBC Take notes during the video. We will be stopping and answering some questions in your INB
50 What are mangroves?Mangroves are various kinds of trees and shrubs that grow in saltwater habitats in the tropics and subtropics.
53 Activity Cut out Mangrove article and paste on right side of notebook Number paragraphsCircle at least 2 vocabulary words per paragraph (pick one color)Read article, underline any important information (another color - no more than 5 words per underline)
54 Create a “1 – Pager”On the left side of the INB (use different color for each)Make a boarder with all the vocabulary words you circled in the articleIn the top ¼ of the page - create a titleNext ¼ draw a picture to represent what you readPick most important vocabulary words and make a mini boarder around your picture.Choose the most important quote from the words that your underlined and rewrite it in the next ¼In the last ¼ of the page, create 1 (or more) higher order thinking question based on the reading…and….Answer the HOT question
55 Share…. Take 3 sticky notes and write your name on them. Visit 3 other notebooks and look at their 1-pagerLeave your sticky notes on the pages you view
56 PhotosynthesisA series of chemical reactions that convert light energy, water and carbon dioxide into the food-energy molecule glucose and give off oxygen.Occurs in the chloroplastsChloroplasts contain the pigment chlorophyll, a chemical that absorbs and reflects light.Leaves appear green because the chlorophyll reflects green light and absorbs all the other colors of light.
58 Cellular RespirationAll organisms require energy (usable power) to survive.Energy is in the chemical bonds in food molecules.Cellular respiration is a series of chemical reactions that convert the energy in food molecules into a useable form of energy called ATP.
59 Cellular Respiration ATP= (adenosine triphosphate) ATP is the energy used for all cellular processes (everything the every cell does)Example: muscle contraction uses 2 million ATP molecules per second. Without ATP we would die.
60 Cellular RespirationCellular Respiration takes place in the mitochondrion of the cells in ALL living things. C₆H₁₂O₆ + 6O₂ CO₂ + 6H₂O + ATP(glucose) (energy)
61 Model of Photosynthesis and Respiration Cut and glue picture on right side under notes.Draw arrows on picture to match website address image for the direction of CO2, H2O and O2.Color carbon dioxide circles orange, oxygen red circles and water blue circles (on picture and legend)
