PASSAGE-1
Have you ever noticed strange bumps on stems, leaves, flowers, or tree branches? Well, they are part of the plant and grown by the plant, but they are homes for tiny insects! These bumps are called galls. Insects form gall. The plant does not decide to grow them. Typically, a female insect lay her eggs on a plant. After baby insects hatch special chemicals are left on the plants. These special chemicals cause the plant to bubble up and form a gall. Once a gall has grown, the insects have a safe place to live and eat. Or do they?
Other animals, besides insects, benefit from gall. Galls are also great places for birds and small animals to find a meal. Woodpeckers, squirrels, mice and bats–all use galls as a source for a tasty insect snack. If a gall has a large hole poked into it a, larger creature may have stopped for a bite.
Now that you know what a gall is, you will probably begin to notice them everywhere. Look around. You may even decide to break open a gall and take a peek inside. If the gall has a little hole,the owner has probably left. Can you believe it? A little house for an insect made by a plant!

[ A ]    the plant to die
[ B ]    no gall to form right
[ C ]    a large gall
[ D ]    a bird to eat the egg
