Gra.s.ses are technically called "graminoids"There are 3 different types of gra.s.ses: Juncaceae (Rushes), Cyperaceae (Sedges, Bullrushes), and Poaceae (Gra.s.ses).
Gra.s.slands are estimated to make up over 20% of the vegetation cover on Earth.
There are over 10,000 types of gra.s.s species in the world.
Scientists have found one species of seagra.s.s in the Mediterranean Sea that dates back to 200,000 years ago making it one of the oldest living organisms that humans have ever discovered.
Gra.s.s is in many of the foods and drinks we consume, including beer, whiskey, and bread. Usually these are in the form of wheatgra.s.s and barley gra.s.s.
It is used for construction materials and as thatch for roofs throughout the world.
The fiber from many gra.s.ses is used in the making of paper.
Gra.s.ses have evolved to grow at their base instead of their tips in order to protect themselves unlike most plants. This allows them to be grazed or burned without receiving any damage to their growing points and allows them to regrow quickly.
