CHAPTER 13- PHOTOSYNTHESIS 🤎 Flashcards
Summarise the process of photosynthesis in two sentences, state where it takes place then write out a balanced equation for photosynthesis (AS level recap)
✅
*State the names of the two main stages of photosynthesis
✅
*Summarize the light-dependent stage of photosynthesis including where it takes place and what occurs during this stage (use keywords in your explanation then define the three keywords to check your understanding)
✅
*Summarize the light-independent stage of photosynthesis including where it takes place and what occurs during this stage (use keywords in your explanation)
✅
*Label all parts of a chloroplast using the diagram in your gallery
✅
*Explain the functions of the following parts of the chloroplast: lamellae (2), thylakoids (membranes and spaces) (3), grana (1), stroma (1) and ribosomes (1)
(you may include more than one function for each organelle)
✅
*Use different chloroplast organelles as examples to explain the relationship between the structure and function of chloroplasts (5 marks)
✅
*Name the four chloroplast pigments
*Explain what photosystems are and the difference between photosystems I and II
✅
*Explain the role of chloroplast pigments as a whole and then the role of each type of chloroplast pigment in light absorption in thylakoids
❌
*Use the diagram in your notes to interprete the absorption spectra of chloroplast pigments (explain your understanding in detail)
✅
*Use the diagram in your notes to interprete the action spectra for photosynthesis (explain your understanding in detail)
✅
State the similarities between the absorption and action spectrum
✅
*Which two processes occur during the light-dependent stage of photosynthesis?
✅
*Explain the process of cyclic photophosphorylation IN DETAIL including all necessary information (use a diagram if necessary)
-state one difference between cyclic and non-cyclic photophosphorylation (long answer question)
✅
*Explain the process of non-cyclic photophosphorylation IN DETAIL including all necessary information (use a diagram if necessary)
-state at least two similarities between cyclic and non-cyclic phosphorylation (long answer question)
