Plant biology is the study of plants, their structure, function, growth, and development. It explores how plants produce their own food through a process called photosynthesis, where they convert sunlight, water, and carbon dioxide into energy. Understanding plant biology helps us learn about ecosystems, agriculture, and the environment. In addition to photosynthesis, plant biology also examines how plants reproduce, adapt to their surroundings, and interact with other organisms. This field includes various topics such as plant anatomy, plant physiology, and plant ecology, all of which contribute to our knowledge of how plants thrive and support life on Earth.
