My speaking text

The professor gives a lecture about the ways that plants protect themselves against insects. First off, she explains physical features of the plants. For example, passion plants have spiky hairs on their leaves which are numerous and dense so no more room is left for the insects to land and eat the plant. These little hairs are physical features of these plants. Secondly, she states that some plants release chemicals to defend themselves against insects. For instance, potato leaves release chemical substances when the insect swallows them and discourages the insects from eating the plant. This chemical makes the insect to feel full and no longer feel hungry so the insect stops eating the plant. Therefore, emitting chemicals is the defensive way of potato plants against insects.
