Grasses (*graminoids*) are plants with narrow leaves growing from the base.
Grasses are the most well known form of monocot. They are typically grown for lawns and as cereals.
By some definitions, grasses are amongst the successful plants alive today due to their coverage of large natural areas (e.g. prairies); plus their large-scale symbiotic relationships with humans (i.e. requiring human intervention to populate huge fields, plus lawns).
