Question

Explain why the leaves only emerge once the growing shoot is above the ground​

Answer 1

Answer:

Your basic vascular plant parts are roots, shoots, stems, and leaves. Of course, there’s a wealth of variety within these types or parts, but it boils down to those four. Each part has distinct functions. Together, these parts reflect how vascular plants evolved to inhabit two distinct environments at the same time: the soil and the air. Why would plants do such a thing? The soil offers water and vital minerals. The air offers carbon dioxide and the energy of sunlight. To forge the successful lifestyles they enjoy today, plants evolved systems to tap into all these resources, both above and below the ground. In short, plants evolved roots and shoots. Shoots, in turn, can develop stems and leaves.
