  • Biology
    • Cells (animal cells)
      • nucleus
      • cytoplasm
      • cell membrane
      • mitochondria
      • ribosomes
      • plants extra cells
        • cell wall
        • permanent vaculoe
        • chloroplatst
      • specialised cells
        • red blood cells
        • guard cells
        • palisade leaf cells
        • sperm and egg cells
      • cell organisation
        • a group of specialised cells form to make a tissue
          • tissues combine together to become an organ
            • organslink together to form an organ system
              • organ system!
    • Photosynthesis
      • Carbon dioxide + water =(chlorophyll) glucose + oxygen
        • chloroplasts contain a green substance called chlorophyll.
          • chlorophyll absorbs sunlight and uses its energy.
            • to convert carbon dioxide and water into glucose,    Also oxygen is a by- product of photosynthesis

      • Rates of photosynthesis
        • The limiting factors of photosynthesis.
          • Carbon dioxide levels.
          • Light Intensity
          • Temperature
        • green house farming
          • green houses trap the suns heat, to make sure that temperature is not a limititing factor.
            • Artificial lights are used to feed the plants light to convert to energy through photosyntheses, so light cannot become a limiting factor
              • We can also increase the ;levels of Carbon Dioxide in a greenhouse by burning a paraffin heater, as a result of tis, Carbon Dioxide is a by-product of this.
