Botany
Botany is the scientific study of plants, including their structure, growth, reproduction, classification, and relationships with other organisms.
Plant cell: A eukaryotic cell with features such as a cellulose wall, chloroplasts, and a large central vacuole. Its distinctive structures underpin plant growth, photosynthesis, and tissue formation.
Photosynthesis: The process by which organisms use light energy to synthesize organic compounds from carbon dioxide and water. It explains how plants capture energy and build much of their biomass.
Theophrastus: An ancient Greek philosopher whose surviving works include systematic descriptions of plants. His plant writings established an early tradition of organized botanical study.
Agronomy: The science and practice of managing crops and soils for food, fiber, and other products. Agronomy applies plant science to crop growth and agricultural production.
Mycology: The scientific study of fungi. Fungi interact with plants as pathogens, decomposers, and mutualistic partners.
Plant tissue: A group of plant cells organized to perform a shared function. Tissues connect cellular structures to the anatomy of roots, stems, and leaves.
Plant hormone: A chemical signal that regulates growth and development in plants. Hormones coordinate responses such as root growth, flowering, and fruit ripening.
Herbal: A book describing plants, often emphasizing their identification and medicinal uses. Herbals preserved practical plant knowledge before modern botanical institutions emerged.
Plant breeding: The deliberate selection and crossing of plants to produce desired inherited traits. Botanical knowledge helps breeders select and improve crop varieties.
Phycology: The scientific study of algae. Algal study borders botany through photosynthetic organisms and the history of plant classification.
