This fully-resourced lesson describes the relationship between the structure of the chloroplast and its role as the site of photosynthesis. The engaging PowerPoint and accompanying resources have been designed to cover specification point 5.7 (i) of the Edexcel A-level Biology B course.
Students were introduced to the ultrastructure of eukaryotic cells in topic 2 so this lesson has been written to build on that knowledge. A version of the quiz show POINTLESS runs throughout the lesson and this maintains engagement whilst challenging the students to recall the parts of the chloroplast based on a description which is related to their function. The following structures are covered in this lesson:
- double membrane
- thylakoids (grana)
- stroma
- intergranal lamellae
- starch grains
- chloroplast DNA and ribosomes
Once each structure has been recalled, a range of activities are used to ensure that key details are understood such as the role of the thylakoid membranes in the light-dependent stage and the importance of ATP and reduced NADP for the Calvin cycle.
This lesson has been specifically written to prepare students for the upcoming lessons on the light-dependent stage and light-independent stage

Topic 5: Energy for biological processes (Edexcel A-level Biology B)
Respiration and photosynthesis are two of the most important biological processes, which can be poorly understood by students but unsurprisingly are commonly assessed in the terminal exams. These 11 lessons have been intricately planned so that they contain a wide range of activities that will engage the students whilst covering the key detail to try to deepen their understanding and include exam-style questions so they are prepared for the assessments. The following specification points in topic 5 of the Edexcel A-level Biology B course are covered by these 11 fully-resourced lessons: * Cellular respiration yields ATP * The different stages of aerobic respiration * The conversion of glucose to pyruvate during glycolysis * The mitochondrial matrix as the site of the Link reaction and Krebs cycle * The production of carbon dioxide, reduced NAD and ATP in the Krebs cycle * Oxidative phosphorylation * The yield of ATP from anaerobic respiration * The production of lactate in mammalian muscles * Ethanol formation in plants * The meaning of the absorption and action spectra * The reason for a variety of photosynthetic pigments in plants * The structure of the chloroplasts * The role of thylakoid membranes in the light-dependent stage * The process of cyclic and non-cyclic photophosphorylation * The use of reduced NADP and ATP in the Calvin cycle * Understand how GALP is used as a raw material in the production of monosaccharides, amino acids and other molecules * Factors that limit photosynthesis including carbon dioxide, light intensity and temperature Due to the detail of these lessons, it is estimated that it will take in excess of a month of A-level lessons to cover these lessons If you would like to sample the quality of the lessons, download the link reaction, Krebs cycle and light-independent stage lessons as these have been shared for free

Topic 5.7: Photosynthesis (Edexcel A-level Biology B)
This bundle contains 5 fully-resourced and highly-detailed lessons which build on the students knowledge of photosynthesis from GCSE and add the fine detail that is critical when tackling questions on this topic in the A-level exams. The lesson PowerPoints and accompanying resources are filled with a wide range of activities that will engage, motivate and challenge the students whilst the detail of the following specification points in topic 5.7 of the Edexcel A-level Biology B course are covered: * The structure of the chloroplast * The role of the thylakoid membranes in the light-dependent stage of photosynthesis * The processes of cyclic and non-cyclic photophosphorylation * The role of the stroma in the light-independent stage * The fixation of carbon dioxide * The use of ATP and reduced NADP from the light-dependent stage in the Calvin cycle * The use of GALP as a raw material * The factors that limit photosynthesis If you would like to sample the quality of these lessons, then download the light-independent stage lesson as this has been shared for free
