1. Plants are multicellular eukaryotic organisms that use photosynthesis to produce their own food. They have tissues and organs like roots, stems and leaves adapted to live on land. 2. Plants are classified into three groups - nonvascular plants (bryophytes), vascular plants without seeds (pteridophytes), and vascular plants with seeds (spermatophytes). 3. Angiosperms are the largest group of spermatophytes and have flowers and fruits containing seeds. They include a wide variety of trees, shrubs and herbs.
