Plants can be defined as multicellular photosynthetic organisms with reproductive structures that are more complex than single cells. By this definition, algae are not considered plants because they are either unicellular or their reproductive structures are essentially unicellular, and fungi, too, are excluded because they are not photosynthetic.

|The Soil and Me: A Perspective on Soil Health||
Soil is the foundation upon which our natural living world depends; it is otherwise known as the dynamic material that civilization is built on (Lindbo, Kozlowski, and Robinson 2012). Soil serves diverse functions that are critical to the survival of humanity; without the soil, life on earth is inconceivable. It represents the critical zone of the earth where life, water, minerals, and air intersect and interact (fig. 1) because the soil constantly relates with other parts of nature. The soil is considered a living, dynamic resource at the earth’s surface and has been defined as “the unconsolidated mineral or organic material on the immediate surface of the earth that serves as a natural medium for the growth of land plants” (SSSA 2015). The thickness or depth of this surface or layer varies with the type and environment of the soil.
