The answer to 'how does grass work' is that grass is a type of plant that grows from seeds and has a complex system of roots, stems, and leaves that work together to absorb water and nutrients from the soil and convert sunlight into energy through photosynthesis. This allows the grass to grow, spread, and thrive in a lawn or garden setting.
Grass blades are the green, leafy parts that we see above the soil. These blades contain chlorophyll, which gives them their green color and allows them to absorb sunlight. The roots of the grass plant grow down into the soil, anchoring the plant and absorbing water and nutrients that the grass needs to survive and grow. The stems, or stolons, spread horizontally across the ground, allowing the grass to spread and form a thick, lush lawn.
