If you increased the light, what will happen to the amount of bubbles?

• more bubbles

• same number of bubbles

• less bubbles

What gas is contained in the bubbles?

• carbon

• carbon dioxide

• oxygen

• methane

An experiment was conducted to investigate photosynthesis. What is the aim of the experiment?
