Grasses

 

 

 

Grass plants grow all over the world. Some grasses are taller than people, but other kinds of grass only grow a few centimeters high. Grasses have roots, stems, leaves and flowers. Grasses need sunlight and water to grow well.

 

 

 

 

 

 

 

 

Some animals eat this thick bamboo.

Bamboo is a very thick, fast-growing grass. Some bamboo can grow five centimeters in just one hour! There are about 8,000 species (types) of grass. Different kinds of grasses grow in different parts of the world. Some grasses or cereal crops, such as wheat, rice and oats, can give us food.

This grass has a very long stem.

Grasses grow quickly when there is enough water. As long as the roots have not been pulled up, grasses can go on growing even when the leaves and stems have been cut or eaten by animals.
