Question 47

Figure 1 shows the modified leaf structures of four different modern plant species: an oak tree (Quercus robur), a cactus (Opuntia spp.), a garden pea (Pisum sativum), and a Venus flytrap (Dionaea muscipula).

Figure 1: Diagram showing the anatomical similarities and different functions of modified leaf structures in four plant species.

Describe how the anatomical structures of these modified leaves provide scientists with evidence for evolution.
