Knowra Plant anatomy Plant anatomy Plant anatomy studies the internal structure of plants, from cells and tissues to organs. It explains how these structures are arranged and connected within roots, stems, and leaves.
Plant cell : A eukaryotic cell with features such as a cellulose-rich wall, plastids, and a large central vacuole. Its walls, organelles, and shape distinguish the basic units found in plant tissues.
Vascular tissue : Plant tissue specialized for transporting water, minerals, and sugars through the body. Its conducting strands link roots, stems, and leaves.
Plant identification : The process of determining a plant's taxonomic identity from observable characters. Internal characters can distinguish species when external features are insufficient.
Marcello Malpighi : An Italian physician and early microscopist whose work helped establish microscopic anatomy. His 1675 plant studies helped bring microscopic structure into botanical investigation.
Plant tissue : A group of plant cells organized to perform shared structural or physiological functions. Anatomy classifies organs by the tissues arranged within them.
Xylem : Vascular tissue that conducts water and dissolved minerals, chiefly from roots toward shoots. Its vessels and tracheids are recognizable internal structures in vascular plants.
Wood : Secondary xylem that forms the structural material of tree trunks, branches, and roots. Its cellular patterns preserve a record of stem structure and growth.
Nehemiah Grew : An English botanist known for early systematic studies of plant structure. His 1682 work described plant tissues and organs through microscopic observation.
Meristem : Plant tissue containing cells that divide and produce new cells for growth. Meristems generate the cells that form primary and secondary structures.
Phloem : Vascular tissue that transports sugars and other organic compounds between plant regions. Its sieve elements and companion cells form the plant's assimilate-conducting tissue.
