Plant biology is a very broad discipline that covers the study of the structure, function and evolution and diversity of plants. Plant biologists study processes at the cellular and whole organisms level, and address questions on how plants respond to the environment and other organisms. Others study the evolutionary history of the huge diversity of plant species.

Plant Biology graduates may find employment in diverse fields, including teaching and research for Universities, Crown Research Institutes and biological industries. Employment opportunities for graduates with good plant biology training are in demand overseas as understanding plant biology is key to solving problems faced by agriculture, the environment and medicine through sustainable technologies.
