Plant Kingdom Review What cycles are needed for plant life? - Carbon-Oxygen Cycle (including Photosynthesis) - Nitrogen Cycle - Water Cycle Let's take a look at the first two... Jan 3 5:33 PM Jan 3 8:20 PM Carbon Oxygen Cycle PHOTOSYNTHESIS takes place in the Carbon Oxygen Cycle. Photosynthesis: is a process that uses light, Carbon Dioxide, and Water to make food (sugar = glucose) and oxygen. Carbon Cycle BrainPOP Ms. Frizzle gets down with the Carbon Oxygen Cycle and Photosynthesis Carbon Oxygen Cycle leads to Photosynthesis!!!! See how! BrainPop on Photosynthesis! Think you understand Photosynthesis? Take the Photosynthesis Quiz Jan 3 8:20 PM Jan 3 7:41 PM NITROGEN CYCLE Animated Nitrogen Cycle Nitrogen Cycle BrainPop Discuss: The atmosphere is 78% nitrogen: why do you think plants and animals can't use nitrogen as it is found in the atmosphere? Explain what is meant by nitrogen fixation. What is the role of bacteria in the nitrogen cycle? Why is nitrogen so important for living things? Jan 3 7:41 PM Jan 3 8:03 PM 1
Plants part 2.notebook Vascular Plants = roots Vascular tubes for transporting nutrients = xylem and phloem. Dry areas Transports materials quickly. Strength Stability Support Grows Tall Divided into two categories Gymnosperms (Cone producing) Angiosperms (Flower producing) Examples: Flowers Trees Grass Dec 16 6:38 PM Non-Vascular Plants = no roots Lack vascular tubes for Transporting Damp, shady places Thin Cell Wall NO roots Absorbs from their surroundings Cannot grow tall Reproduce using spores Have Rhizoids: a root like structure that helps "cling" plant to the ground. Examples: Moss Liverworts Hornworts Dec 16 6:27 PM Root Types (PG. 95): Domain: Eukarya Kingdom: Plant VASCULAR PLANTS! Root Types: Fibrous = many branching roots (ex. grass, trees, green onions etc.) Tap = 1 main root (ex. dandelions, carrots, radishes, beets, etc.) Prop = grows from the stem and supports the stem above ground roots grow above ground... almost like pillars for the stem (ex. corn, mangroves, etc.) Feb 24 8:39 AM Jan 4 12:08 PM Root Types (pg. 95) Parts of the Root: Root cap- root end that dissolves into soil tip of root(s) protects root. Root hairs- absorbs water Fibrous Root or Tap Root???? How do Roots absorb H2O? ANSWER: OSMOSIS = movement of fluid from a greater solution (the ground water) to weaker solution (the plant). Note: This is the absorption process. Jan 3 7:26 PM 2
Plants part 2.notebook Roots + Stems (pg. 105) How does H20 get to other parts of the plant? ANSWER: DIFFUSION: spreading of the solution to other parts. Note: This is the spreading out process. Osmosis and Diffusion go hand in hand! Roots + Stems (pg. 105) Plant Structures: Stem Provides support Holds leaves towards sunlight Tissues in stem transport food and water throughout the plant Parts of Stem: xylem- transports water up toward leaves phloem- transports food made in leaves (photosynthesis) down to the rest of the plant pith- stores food in the center of the stem Types of Stems Herbaceous (no wood stem) Woody (wood stem) Dec 16 5:55 PM Osmosis/diffusion pg 100 in 1) NB 3/13/12 Notes When osmosis occurred the water in the cells of the plant were high concentration and then moved out torwards the low concentration causing to wilt 2) Stay The same size ) The red blood cell Will grow b/c The higher concentration of water is outside of the cell No diffusion b/c Of The cell wall it would move in by osmosis 5. Too much water Mar 2 6:55 AM Plant Structures: Leaves Green in color due to the green pigment called chlorophyll Chlorophyll is found in chloroplast of the plant cell Chloroplasts traps the energy in sunlight On the underside of the leaf are tiny little openings called stomata that allow gases to pass Photosynthesis needs: Sun, water, and Co2 Mar 13 8:22 AM Cellular Respiration Respiration: a process by which an organism releases (uses) energy... CELLS go through respiration. They use the glucose. A plants stored energy is? For photosynthesis plants need: For respiration plants need: What does the roots do for Photosynthesis? What does the stoma do for photosynthesis? Photosynthesis and Respiration are OPPOSITES! Both happens in the leaves of plant. What does the chloroplast with the chlorophyll pigment do for the plant? Glucose (C6H12O6)+6O2 6CO2+6H2o+ATP Energy Formula for Photosynthesis CO2+H2O sun Glucose (C6H12O6)+ Oxygen (O2) Dec 18 1:41 PM Jan 4 12:38 PM 3
epidermis is the outer layer: protects the inside when it get cold the water is not given to the leaf, so Chlorophyll traps the sun's radiant energy photosynthesis stops in the fall Needs water, sun, and CO2 Can store sugar in the pith plants use the suns energy to make food Even if you don't eat plants you get the glucose from plants from the meat you eat The animal you are eating ate plants. Photosynthesis Movie Some protist Glucose and oxygen is made in photosynthesis CO2+H2O+sun glucose (C6H12O6)+ O2 use photosynthesis stoma is called a mouth. It is opened by the guard cells. It lets out water in a process called transpiration Glucose is sugar, which is plant food Plants need glucose for energy Photo means light Sythesis means putting together We breathe in O2 that plants make and when we breathe out CO2 which plants need Bacteria can be autotrophs and use photosynthesis Oxygen is used for cellular respiration Starch in plants is glucose C6H12O6 Cellular respiration breaks the glucose down to chemical energy.

Gymnosperms = produces "naked" seeds and have needle like or scale like leaves. Angiosperms = produces a seed enclosed in fruit (fruit is ovary of flower) and/or produces flowers. *BOTH REPRODUCE SEXUALLY! Notes 3/15/12 Jan 3 8:17 PM Mar 15 6:46 AM Gymnosperm Diagram: Gymnosperms vs. Angiosperms Cone bearing *female pine cone (bigger than male pine cone) don't produce a flower. female pine cones stay in the tree sperm *Sap helps hold pollen in place. *Pollen forms seed naked (helicopter) *Seed flys away (wind) In the scale Wind is the pollinator. at the end of the scale in the female cone is the ovary, Angiosperms (Vascular Plants) Angiosperms = produces a seed enclosed in fruit (fruit is ovary of the flower) and produces flowers. Take a look at the parts of the flower and their definitions! How does a flower... become a fruit???? Jan 3 8:17 PM Jan 4 12:25 PM 5
