The Fascinating World of Japanese Barberry (Berberis thunbergii f. atropurpurea)
What is a Plant?
Plants are living organisms that belong to the kingdom Plantae. They are characterized by their ability to photosynthesize, which means they can convert light energy into chemical energy stored in the form of carbohydrates. This process is crucial for their survival and serves as the foundation of most ecosystems on Earth. Plants come in a wide variety of shapes, sizes, and colors, and they play vital roles in providing food, shelter, and oxygen for other living beings. They are also a source of numerous raw materials, such as wood, fibers, and medicinal compounds.
