This fully-resourced lesson describes the components of the chloroplast, focusing on the grana and stroma as the sites of photosynthesis. The engaging PowerPoint and accompanying resources have been designed to cover point 5.2.1 (b) of the OCR A-level Biology A specification and has been specifically designed to introduce students to the light-dependent and light-independent stages before they are covered in detail in upcoming lessons.
Students were introduced to eukaryotic cells and their organelles structures in module 2.1.1 so this lesson has been written to test and 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 reactions and the importance of ATP and reduced NADP for the reduction of GP to TP in the Calvin cycle. Links to other topics are made throughout and this is exemplified by the final task of the lesson where students are challenged on their recall of the structure, properties and function of starch (as originally covered in module 2.1.2)

Module 5.2: Photosynthesis & Respiration (OCR A-level Biology A)
Photosynthesis and respiration are two of the most commonly-assessed topics in the terminal A-level exams but are often poorly understood by students. These 16 lessons have been intricately planned to contain a wide range of activities that will engage and motivate the students whilst covering the key detail to try to deepen their understanding and includes exam-style questions so they are prepared for these assessments. The following specification points in modules 5.2.1 and 5.2.2 of the OCR A-level Biology A course are covered by these lessons: * The structure of a chloroplast and the sites of the two main stages of photosynthesis * The importance of the photosynthetic pigments * Using thin-layer chromatography to separate photosynthetic pigments * The light-dependent stage of photosynthesis * The fixation of carbon dioxide and the light-independent stage of photosynthesis * The uses of triose phosphate * Factors affecting photosynthesis * The need for cellular respiration * The structure of the mitochondrion * The process and site of glycolysis * The link reaction and its site in the cell * The process and site of the Krebs cycle * The importance of coenzymes in cellular respiration * The process and site of oxidative phosphorylation * The chemiosmostic theory * The process of anaerobic respiration in eukaryotes * The relative energy values of carbohydrates, lipids and proteins as respiratory substrates * The use of the respiratory quotient Due to the detail of these lessons, it is estimated that it will take in excess of 2 months of A-level lessons to cover this module If you would like to sample the quality of the lessons, download the uses of triose phosphate, link reaction and respiratory substrates lessons as these have been shared for free

Module 5.2.1: Photosynthesis (OCR A-level Biology A)
This lesson bundle contains 7 fully-resourced lessons which will engage and motivate the students whilst covering the content of module 5.2.1 of the OCR-A-level Biology A specification in the depth of detail required to support them to answer assessment questions on this topic of PHOTOSYNTHESIS confidently. This cellular reaction can be poorly understood by students so intricate planning has gone into the design of the lesson PowerPoints and accompanying resources to ensure that key details are embedded and reinforced throughout and that knowledge acquired in previous lessons is regularly checked. The following specification points are covered by the lessons in this bundle: * The structure of the chloroplasts and the two main stages of photosynthesis * The importance of photosynthetic pigments for photosynthesis * Using thin-layer chromatography to separate photosynthetic pigments * The light-dependent stage of photosynthesis * The fixation of carbon dioxide and the light-independent stage of photosynthesis * The uses of triose phosphate * Factors affecting photosynthesis If you would like to sample the quality of the lessons, then download the "uses of triose phosphate" lesson as this has been shared for free
