Q1. (a) Complete the word equation for photosynthesis. Use words from the box. chlorophyll minerals oxygen water carbon dioxide + ........................ glucose + ........................ → (2) (b) Plants may grow faster if they have more carbon dioxide. Indigestion tablets dissolve in water to form a solution. This solution slowly gives off carbon dioxide. A student set up an investigation to see what concentration of carbon dioxide is best for increasing the growth of geranium plants. The student: put a geranium plant in a clear plastic bag put a dish containing water and one tablet in the bag sealed the top of the bag. The student: set up 5 more experiments each with water and a different number of tablets left all the plants in a well-lit place for four weeks. The student used a clear plastic bag, not a black plastic bag. Explain why.
