👉 Silvical is a term used in the field of biology to describe a type of plant that produces siliceous minerals, such as calcite, silex, and dolomite. Siliceous plants are characterized by their ability to form calcium carbonate structures, which are essential for supporting life on Earth's surface. These plants were once considered to be primitive forms of life, but over millions of years, they have evolved into complex multicellular organisms that can survive in a wide range of environments
