Chlorophyll is a green pigment found in plants, algae, and some bacteria, playing a crucial role in photosynthesis. It absorbs light energy, primarily from the sun, and converts it into chemical energy, allowing plants to produce food from carbon dioxide and water. This process not only sustains the plant but also releases oxygen into the atmosphere, which is vital for life on Earth. There are several types of chlorophyll, with chlorophyll-a and chlorophyll-b being the most common in higher plants. The presence of chlorophyll gives plants their green color, making it easy to identify them in nature. Without chlorophyll, the process of photosynthesis would not occur, leading to a collapse of the ecosystem.
