Photosynthesis, Diffusion and Osmosis (Foundation Tier)

A little quic to test your knowledge on photosynthesis, diffusion and osmosis. Hope this is helpful for your OCR 21st Century Additional exams!

HideShow resource information
What is the word equation for photoynthesis?
Carbon dioxide + water > glucose + oxygen
1 of 5
Light energy is required in photosynthesis. What chemical absorbs light enegry?
Chlorophyll
2 of 5
What is diffusion?
Diffusion is a chemical process in which particles spread from a region of high concentration to a lower concentration (they diffuse down a conentration gradient).
3 of 5
A partially permeable membrane separates two solutions; pure water and a dilute solution. Which is higher in concentration? Pure water or the dilute solution? Explain your answer.
Pure water - The particles will spread FROM the pure water TO the dulite solution, so the particles will diffuse down a concentration gradient.
4 of 5
What are the three limiting factors of photosynthesis?
Light intensity, carbon dioxide concentration and temperature.
