Lesson 11: Photosynthesis- nutrition in plants

Hi,

Here are some 31 colourful and cheerful powerpoint slides to zest up your revision of this topic. the concepts covered by these slides include:
  • organisation of plant-cells, tissues, organs, systems and organism
  • specialised cells, adaptation for their functions
  • palisade cells-contain chloroplasts for photosynthesis
  • root hair cells-have large surface area to volume ratio for quick absorption of water and dissolved mineral ions
  • guard cells- bean shaped, have unevenly thickened wall for gaseous exchange with the environment
  • pollen cells- sex cells for adaptation for pollination, used for sexual reproduction
  • annotated plant cells
  • mitochondria-site of cellular respiration
  • chloroplast-site of photosynthesis
  • plants are producers in the ecosystem- change sunlight energy into chemical energy aka glucose molecule
  • glucose- a carbohydrate which the plant will use to change into proteins, fats and other forms of carbohydrates
  • uses of glucose in plant-respiration, 80% efficiency in changing it to other froms and for storage
  • cross section of leaf, annotated
  • equation for photosynthesis, models to illustratae the synthesis from water and carbon dioxide
  • short questions




Cheers
