How does the stem of the grass ensure the grass gets sufficient light for making food?

The stem of the grass, known as the culm, supports the leaves and elevates them above the ground, allowing them to capture sunlight more efficiently. Its structure enables the leaves to spread out and maximize exposure to sunlight, which is essential for photosynthesis. Additionally, the stem helps to maintain the overall stability of the plant, ensuring that the leaves remain oriented towards the light source and can photosynthesize effectively.
