Chapter 37.1, Problem 1LO
Summary Introduction
To explain: The way in which soil interacts with negatively- and positively-charged ions.
Introduction: Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The soil is defined as the inorganic and organic material present on the Earth’s surface. Most of the activities that support the life of a plant are hidden inside the soil. The soil is composed of ingredients that include rocks of various sizes, sand, silt, clay, and humus.
