A.1.3—Tables, diagrams, bar charts and histograms question 1

[Maximum number: 3]

Light is essential for photosynthesis.

The photograph shows thale cress, a small flowering plant found in Europe, Asia and Africa.

Figure for Question A.1.3—Tables, diagrams, bar charts and histograms question 1 — Edexcel A-Level Biology A2

The effect of wavelength of light on thale cress was investigated. Three groups of plants were treated with a different wavelength of light. One group of plants was treated with blue light, one group with amber light and one group with red light. The following were measured: - rate of photosynthesis - leaf biomass - pigment content of the leaves - changes in transcription of genes in the leaves. Another group of these plants had a control light shone on them.

The table shows the results for the pigment content of the leaves.
