What is grass?

Grasses are monocotyledonous flowering plants that are widely grown. They are found in grassland, lawns, wetlands, forests, and tundra. They constitute 45% of the world’s vegetation. Grasses are well diverse consisting of over 12,000 species in 780 genera. 

Some grasses are tall and are almost classified as trees such as the bamboo grass. They are perennial herbs. They possess small stems called culms, and leaves are placed at the nodes. Some of them have developed coping mechanisms to avoid being grazed on. 

For example, sword grass has silica phytoliths that harden the leaves and are sharp to the extent of causing mechanical injury to humans. Napier grass contains spines that irritate the eyes and noses of grazing animals. 

Which grasses are beneficial to humans?

Various grasses are useful to humans they include:

  • Lemon grass
  • Nappier grass

Some grasses are also processed to provide grass fiber that is used in the making of biofuels, nonwoven fabric, and as reinforcements for plastics. Long, hardy and leafy grasses are used in the thatching of traditional houses. 

Grasses are also used in water treatment in wetlands. They provide barriers that act as water filters. Grasses are also used in land reclamation practices by the provision of vegetative cover. 

Grasses are also used as ornamental plants. This is due to their ability to cover large areas and their dense color. They are used in lawns, fields, and grasslands.
