What is a Plant?
Plants are vital organisms that play a crucial role in the Earth’s ecosystem. They are characterized by their ability to produce their food through the process of photosynthesis. This process involves the uptake of carbon dioxide, water, and sunlight to produce energy in the form of glucose. This vital function not only sustains plant life but also provides the necessary oxygen for other living organisms. As a plant scientist, it is fascinating to explore the diverse range of plants, each with its unique characteristics and requirements for growth and survival.
