The answer to 'how does grass work' is that grass is a type of plant that grows from seeds and has a complex root system that helps it absorb water and nutrients from the soil. Grass blades grow up from the ground, and the roots grow down, anchoring the plant in the soil. As the grass grows, it spreads outward to form a dense, lush carpet of green that can cover large areas of land.
Grass is a resilient plant that can withstand a lot of foot traffic and environmental stresses, like changes in temperature and precipitation. It has the ability to self-repair by spreading its roots and sending up new blades to replace damaged or dead ones. This makes grass an ideal ground cover for lawns, parks, and other outdoor spaces.
