Plants are living organisms that belong to the kingdom Plantae. They are characterized by their ability to perform photosynthesis, a process that converts sunlight into energy using chlorophyll, a green pigment found in their leaves. Most plants have roots that anchor them to the soil, stems that support their structure, and leaves that capture sunlight. Additionally, plants can be classified into various types based on their characteristics. For example, flowering plants produce flowers and seeds, while non-flowering plants reproduce through spores. Plants also vary in size, shape, and habitat, ranging from tiny mosses to towering trees, adapting to different environments around the world.
