|Description:||Plant Biology is the study of plant biology. As the first multi-cellular organisms to live on land, plants paved the way for life above the water. They produce the oxygen we breathe, purify the air and affect the climate by absorbing carbon dioxide, which acts as an insulating blanket around Earth. The contribution of plants to life on Earth is enormous, yet they require little more than sunlight and water to grow and flourish. Most food chains begin with plants as primary producers. Plants provide wood for furniture and homes, cotton for clothing, ingredients for medicines and much more.
Students of Plant Biology study photosynthesis, the chemicals plants produce to protect themselves from micro-organisms and animals. They also learn about plant anatomy (arrangement of cells), morphology (body organization), physiology (function of cells, tissues and organs), biochemistry, molecular biology and development.
