Plants are a major group of living organisms that are characterized by their ability to produce their own food through photosynthesis. They are typically multicellular eukaryotes, and their cells possess cell walls made of cellulose. Most plants are sessile, meaning they are rooted in one place and do not move freely. Their life cycle typically involves alternating between a diploid sporophyte generation and a haploid gametophyte generation.

The plant kingdom encompasses a vast diversity of forms, from microscopic algae to towering trees. Key groups within plants include mosses, ferns, conifers, and flowering plants (angiosperms). Flowering plants are the most diverse and widespread group, distinguished by the presence of flowers and fruits, which aid in reproduction. Plants play a crucial role in ecosystems, providing oxygen, food, and habitat for countless other organisms. They are fundamental to life on Earth, forming the base of most food chains and influencing climate and soil composition. Humans rely heavily on plants for food, medicine, building materials, and countless other resources.
