finding about photosynthes

Finding out about photosynthesis Date: __________ Partners: ____________ Aim: To be able to explain the conditions necessary for photosynthesis and to compare experimental results to a control. To recognise tests for some inorganic substances found in plants. Materials: „h A plant with variegated leaves in a pot which has been in the dark for 24 hours prior to the class „h Iodine „h Alcohol „h Potassium hydroxide „h Hotplate (or Bunsen burner with tripod) „h Petri dish „h …showed first 75 words of 1365 total…

Conclusion: During this practical report I have learnt that there are three main factors that must be present for photosynthesis to occur. They are Carbon dioxide, light and chlorophyll. As a result of this experiment I have discovered that if a plant is deprived of light or carbon dioxide for a period of time it begins to use up its starch deposits to make food for its self.
