Photosynthesis

  1. 1. PHOTOSYNTHESIS EL REDIN SCHOOL SCIENCE YEAR 5 MADE BY MR. FELIPE
  2. 2. WHAT IS PHOTOSYNTHESIS? Itistheprocesswhichenablesplantstomakefoodfrom:
  3. 3. • Water • Carbondioxide • Sunlight
  4. 4. WHERE DOES IT TAKE PLACE? • Photosynthesistakes place in theleavesandothergreenplantcells
  5. 5. HOW DOES PHOTOSYNTHESIS WORK? (thephotosynthesisprocess) • Step 1: Mineralsfromthesoildissolve in water Minerals + water = RAW SAP
  6. 6. • Step 2: plantsabsorbtheRAW SAP fromthesoilthroughtheirROOTS andROOT HAIRS
  7. 7. • Step 3: theRAW SAP travels up theSTEM totheLEAVES through long tubescalledXYLEM VESSELS
  8. 8. • Step 4: CARBON DIOXIDE enterstheplantthroughtinyporesontheundersurface oftheLEAVEScalledSTOMATA
  9. 9. • Step 5: insidetheLEAVES, theRAW SAP mixes withtheCARBON DIOXIDE andbecomesGLUCOSE. CHLOROPHYLL is a greensubstance in . theleaveswhich traps SUNLIGHT. Sunlightisesentialforphotosynthesis, so itonlytakes place duringtheday.
  10. 10. • Step 6: GLUCOSE isdistributedfromtheLEAVES toallpartsoftheplantthroughtubescalledPHLOEM VESSELS. Plantsgive off OXIGEN as a wasteproductofphotosynthesis
  11. 11. RESPIRATION • PlantstakeOXYGENfromtheairandgive off CARBON DIOXIDE. They combine OXIGENwithnutrientstogetenergy. • This gas exchangeiscalledRESPIRATION. Ittakes place in theleaves ALL THE TIME, dayand night
  12. 12. RESPIRATION • Plants produce more oxygenthanthey use. As a result, forestsandjungles are importantforus as sourcesofoxygen
