How do grasses typically grow from the seed?

Grasses have a unique growth pattern that is characterized by the development of fibrous root systems. When grass seeds germinate, the initial root growth leads to the establishment of a dense network of thin, fibrous roots. This allows grasses to effectively absorb water and nutrients from the soil, which is crucial for their growth and survival.

The fibrous root system contributes to the stability of grasses in various soil types and is adept at preventing soil erosion. Unlike other plants that may produce a taproot, grass roots spread out horizontally, helping them to cover larger areas and access moisture more efficiently.

The other options present different characteristics that do not accurately describe the typical growth pattern of grasses from seed. Broad leaves appearing immediately is not characteristic of grasses; they often start with thin, elongated leaves. A growing point located above the soil surface is more typical of some types of plants but not grasses, as their growing points are generally at or near ground level, allowing them to remain protected. Lastly, while certain plants might not have visible leaves until maturity, grasses usually have leaves that emerge soon after germination. Therefore, option B accurately encapsulates an essential aspect of how grasses establish themselves from the seed.
