(a(ii))[1]
State the name of the green substance needed by plants for photosynthesis.
(b(i))[1]
State the temperature at which the aquatic plant produced the greatest number of gas bubbles in two minutes.
(b(ii))[1]
Use Fig. 2.2 to determine the number of gas bubbles produced by the aquatic plant, in two minutes, at $15\degree C$ and at $25\degree C$.
(b(iii))[2]
Use your answer to (b)(ii) to calculate the percentage increase in the number of gas bubbles produced by the aquatic plant at $15\degree C$ and $25\degree C$. Show your working.
(c)[3]
Describe the results shown in Fig. 2.2.
(d)[1]
State one factor, other than temperature, that affects the rate of photosynthesis.
