Plantae (Kingdom)

Plantae, or the plant kingdom, includes all green, photosynthesizing organisms such as trees, flowers, grasses, and ferns. These organisms mainly produce their own food using sunlight, water, and carbon dioxide through a process called photosynthesis. Plants have cell walls made of cellulose and typically have roots, stems, and leaves. They form the foundation of most ecosystems by providing oxygen, food, and shelter for many other organisms. Plants also play a vital role in maintaining the environment by absorbing carbon dioxide and stabilizing the soil. Overall, they are essential for life on Earth, supporting both natural ecosystems and human needs.
