The content can be developed better:
In the lecture, the professor talks about the two ways plants protect them from being eaten by insects. The first is that they use physical features that make it hard for insects to land on them. Passion plants have spiky hairs all over them, no room is left for insects to land on the leaves in order eat them. The second kind of defense is chemical. Take the potato plant for example, it can release a chemical from its leaf system when being eaten by insects. The insect swallows this chemical which makes it feel full, like it’s already had enough to eat. Because the insect doesn’t feel hungry any longer, it stops eating the plant.
