Photosynthesis Unit 4 3.0 / 5 based on 4 ratings ? BiologyCellular processes and structureA2/A-levelAQA Created by: SamanthaCreated on: 04-01-13 16:19 Where does photosynthesis take place? In the chloroplast of the plant cell 1 of 16 What do chloroplasts contain of? A double membrane, thylakoids, lamellae, photosynthetic pigments, stroma and starch grains 2 of 16 What do thylakoids stack up into? Grana 3 of 16 What do the lamellae do? Link grana molecules 4 of 16 What are two photosynthetic pigments? Chlorophyll and carotene 5 of 16 What are photosynthetic pigments? Coloured substances that absorb light energy for photosynthesis 6 of 16 Where are photosynthetic pigments found and what are they attached to? They are found in the thylakoid membrane and are attached to proteins 7 of 16 What is the protein and pigment called? A photosystem 8 of 16 How many photosystems do plants use to capture light energy? Two 9 of 16 How are photosystems 1 and 2 different? 1 absorbs light at 700nm and 2 absorbs light at 680nm 10 of 16 What is the stroma? A gel liquid which fills the chloroplast and surrounds the thylakoids 11 of 16 What does stroma contain? Some sugars, enzymes and organic acids 12 of 16 Are carbs produced by photosynthesis used up straight away? No 13 of 16 What are carbs stored as and where are they stored? They are stored as starch grains in the stroma 14 of 16 What is the chemical equation for photosynthesis? 6CO2 + 6H2O -------------> C6H12O6 + 6O2 15 of 16 What are the names of the two stages that photosynthesis takes place in? Light dependent and light independent stages 16 of 16
