follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica
