Fig. 8.1 shows a palisade cell taken from a leaf. With label lines and the letters X, Y and Z, identify in Fig. 8.1 a structure that: • contains RuBP - X • is fully permeable - Y • is made mainly of phospholipids - Z
Fig. 8.2 shows the apparatus used in an experiment investigating how light intensity affects the rate of photosynthesis in an aquatic plant.
Use the data in Table 8.1 to draw a graph showing how light intensity and the rate of photosynthesis are related.
Using the values in Table 8.1, draw a graph to show how light intensity is related to the rate of photosynthesis.
Explain the pattern of the graph you have drawn, referring to limiting factors.
Name the accessory pigment(s) shown in Fig. 8.3.
Outline how the accessory pigments function in photosynthesis.
Only a small amount of light of wavelength $550\ \text{nm}$ is absorbed by the photosynthetic pigments. State what happens to most of this light.
A graph may also be drawn to show how wavelength of light is related to the rate of photosynthesis. State the name of this type of graph.
