  1. Natural Science

  2. Unit 1: Plants Importantvocabulary • Root = raíz • Stem = tallo • Leaf/leaves = hoja(s) • Vessel= vaso • Soil= tierra

  3. Characteristics of plants • Plantsdon’tmove. • Plants produce theirfood. • Plants are living things. • Plants’ mainorgans are: roots, stem and leaves Parts of a plant • Leaves: • They capture sunlight and carbondioxide. • Theymakenutrients. 2. Stems: 1. Theykeeptheplantupright. 2. Theycarrywater and mineralsthroughvessels. 3. Thetrunk of a treeis a thickstem. 3. Roots: 1. Theytakewater and mineralsfromthesoil.

  4. Classification of plants

  5. Respiration Plantsgetenergythroughrespiration. Plantsabsorboxygenfromthe air. Theoxygen and nutrients are transformedintoenergy. Theplantreleases (expulsar)carbondioxide. Plantsneedenergy 24 hours a day.

  6. How do plantsmaketheirnutrients? • Therootsabsorbwater and mineralsfromthesoil. This mixture iscalledrawsap (sabia bruta). • Xylemvessels (vaños leñosos) carrytherawsapfromtherootstotheleaves. • Leavesabsorbcarbondioxidethroughtheirstomata. • Photosynthesisoccursinsidetheleaves. ThechlorophylltrapsenergyfromtheSun. Sunlighttransformsrawsap and carbondioxideintonutrients (= glucose = elaboratedsap (sabia elaborada)) Theplant expelsexcessoxygenthroughtheirstomata. 5. Phloemvessels (vasos liberianos) transportelaboratedsapallovertheplant.

  7. P. 18 ex 3 • P. 19 ex 4. • Roots --- absorbwater and minerals • Stems---- distributesubstances • Leaves --- Produce oxygen • Flowers --- sexual reproduction

  8. P. 19 ex 7 • A. Substancesthat are neededforphotosynthesistooccur: Carbondioxide, minerals, water and sunlight. • B. Substancesmadeduringphotosynthesis: nutrients • C. Substancesreleased (expulsadas) thoughphotosynthesis: oxygen • D. Energyneededforphotosynthesistooccur: Sunlight p. 19 ex 9 Mosses --- no roots, stemsorleaves Ferns --- no flowers Gymnosperms --- no fruit Angiosperms --- fruit
