Recently, we have learnt that we have five _36_. Our teacher asked us to find out whether plants have them too. After some research, we found that it is more _37_ that plants have just one or two senses, which is quite different from humans.

Some plants can sense the light from the sun, and grow towards _38_. What is amazing is that plants which like eating small insects can sense the soft touches of the insects on their leaves. After they sense the insects near them, they move their leaves all of a sudden to _39_ them. It has also been discovered that some plants can feel _40_ the animals want to hurt them or not. No one knows _41_ the plants can do this. The results of a recent experiment _42_ out by some scientists are amazing. It is observed that when plants _43_ dangerous insects, they give off a kind of smell for _44_, because the smell can attract other insects in the _45_ to kill the dangerous ones. How clever plants are!
