Botanists study all types of plants. Their studies cover growth, reproduction, population, commercial value, relationships between plants, and the biological structure and function of plants. The plants studied by botanists include everything from tiny water plants to large trees.
Most botanists specialize in one particular area of study. For example, some botanists specialize in the structure of plants. Others specialize in plant ecology in a particular environment or improving a certain group of plant crops for food. Botanists work for universities, teaching or researching, and for the government in public gardens, parks and arboretums. Others work for corporations in the areas of plant development or in finding new uses for plants.
