Plants show morphological plasticity and can change their morphology in response to different environmental conditions. Four figures (A to D) show simplified diagrams of a plant’s typical response to environmental conditions, compared against a standard morphology.

Figure 1. Figure 1.

Using the information and data, determine which of the statements are true or which are false.

matching responses to diagrams. Match the statements (a: response to soil fertilization, b: response to apical damage, c: response to shade condition, d: response to trampling pressure) with the corresponding diagrams (A to D) and choose the appropriate number from the table.
