AQA GCSE Biology – Photosynthesis Exam Questions and Answers

AQA GCSE Biology – Photosynthesis Exam Questions and Answers What is the word equation for photosynthesis? - Answer️️ -Carbon dioxide + Water -> Glucose + Oxygen What is the symbol equation for photosynthesis? - Answer️️ -6CO2 + 6H2O -> C6H12O6 + 6O2 What is the name of the green pigment used in photosynthesis? - Answer️️ - Chlorophyll What is the role of the chloroplast? - Answer️️ -Photosynthesis Give 5 ways that root hair cells are adapted - Answer️️ -1. Hairs give large surface area 2. No cuticle just a thin membrane 3. Thin cell wall 4. Large permanent vacuole to store water 5. Close to the xylem How are xylem cells adapted? - Answer️️ -Lignified walls to prevent water loss, bordered pits which allow water out in the correct place, lignification means the cells are all dead. There are no end walls (it's just one continuous tube) How are phloem cells adapted? - Answer️️ -Thin walls, contain cytoplasm but no nucleus - companion cells control activities of phloem cells, have sieve plates (perforated walls) in between cells How is the leaf adapted for efficient photosynthesis on a cellular level? - Answer️️ -1. Waxy cuticle prevents water loss, 2. Palisade cells contain chloroplasts and are regular
