Question

Match the following:
1.Carbon dioxide and water
a. A higher carbon dioxide concentration
2. Formation of glucose
b. The two reactants in the photosynthesis reaction
3. Speed up the process of photosynthesis
c. Carbon dioxide from the air and hydrogen from water molecules are combined

  1. 1 - b, 2 - a, 3 - c
  2. 1 - b, 2 - c, 3 - a
  3. 1 - c, 2 - b, 3 - a
  4. 1 - a, 2 - b, 3 - c

The correct answer is: 1 - b, 2 - c, 3 - a


    • Carbondioxide and water reacts in the presence of sunlight to form glucose and water
    • This glucose is made up of carbondioxide from air and hydrogen from water. It acts as fuel for the cell
    • A higher concentration of carbondioxide increases the rate of photosynthesis
