Why do plants grow in some places and not in others Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the earth only a few unusual plants can grow. That’s why dry deserts are almost not covered with trees or grass.
Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach A few plants, such as
beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.
1. According to the passage, plants need ________ things to grow well.
A. two B. three C. four D. five
2. From the passage, we can know it is ________ for plants to grow in dry places.
A. easy B. difficult C. impossible D. important
3. The reason why most plants can’t grow on the sandy beach is that .
A. there isn’t enough sunlight B. there is too much water
C. it is too crowded there D. it has little food for plants
