The plant kingdom encompasses a diverse group of organisms that possess the ability to photosynthesize, converting sunlight into energy. It includes various plant types such as mosses, ferns, conifers, and flowering plants. Plants are characterized by their multicellular structure, cell walls made of cellulose, and the presence of chlorophyll. They play a crucial role in ecosystems, providing oxygen, food, and habitat for other organisms. Plants also have economic significance, being used for food, medicine, shelter, and aesthetic purposes.
