ARS plant physiologist James Bunce studies water use by barley grown in a greenhouse with elevated atmospheric carbon dioxide.A plant physiologist studies the life processes in plants. Plants look like they basically just sit there in the soil. But they can be very busy with photosynthesis, taking in carbon dioxide and giving off oxygen, and responding to light, temperature, moisture, insect pests and chemicals—to name only a very few. A plant physiologist might specialize in one particular process or become an expert in one particular plant.
