Photosynthesis (Edexcel A-level Biology A)

The 4 lesson PowerPoints included in this bundle are highly detailed and along with their accompanying resources, they have been designed to engage and motivate the students whilst the Pearson Edexcel A-level Biology A (Salters Nuffield) specification points concerning photosynthesis are covered.

These specification points are 5.5, 5.7, 5.8 (i) & (ii) and 5.9 and these state that students should:

• Understand the overall reaction of photosynthesis as requiring energy from light to split apart the strong bonds in water molecules, storing the hydrogen in a fuel (glucose) by combining it with carbon dioxide and releasing oxygen into the atmosphere.
• Understand the light-dependent reactions of photosynthesis including how light energy is trapped by exciting electrons in chlorophyll and the role of these electrons in generating ATP, reducing NADP in photophosphorylation and producing oxygen through photolysis of water
• Understand the light-independent reactions as reduction of carbon dioxide using the products of the light-dependent reactions (carbon fixation in the Calvin cycle, the role of GP, GALP, RuBP and RUBISCO).
• Know that the products are simple sugars that are used by plants, animals and other organisms in respiration and the synthesis of new biological molecules (polysaccharides, amino acids, lipids and nucleic acids).
• Understand the structure of chloroplasts in relation to their role in photosynthesis.
