Vegetative parts of flowering plants

• Root Cap - Parenchymatous, protective apex of root.
• Root Hair - Lateral, absorbing outgrowth of the epidermal cell.
• Secondary Root - Lateral root with root cap and hairs, derived from the pericycle.
• Bud - Immature vegetative or floral shoot or both, often covered by scales.
• Flower - Reproductive structure of flowering plants 
• Fruit - Matured ovary of flowering plants
• Leaf - A photosynthetic and transpiring organ
• Root - An absorbing and anchoring organ
• Seed - Matured ovule of seed plants
• Stem - A supporting and conducting organ usually developed initially from the epicotyl and

  growing upward
• Bark - Tissues of plant outside wood or xylem.
• Pith - Centermost tissue of stem, usually soft.
• Wood - Xylem consisting of vessels and/or tracheids, fibers, and parenchyma cells
• Bud Primordium - Meristematic tissue that gives rise to a lateral bud.
• Flower Primordium - Meristematic tissue that gives rise to a flower.
• Leaf Primordium - Meristematic tissue that gives rise to a leaf.
• Promeristem - Apical growing or meristematic tissue that gives rise to other bud parts.
• Scale - Protective leaf on outside of bud.
• Blade - Flat, expanded portion of leaf.
• Leaflet - A distinct and separate segment of a leaf.
• Ligule - An outgrowth or projection from the top of the sheath, as in the Poaceae.
• Midrib - The central conducting and supporting structure of the blade of a simple leaf.
• Midvein - The central conducting and supporting structure of the blade of a leaflet
• Petiole - Leaf stalk.
• Petiolule - Leaflet stalk.
• Pulvinus - The swollen base of a petiole or petiolule.
• Rachilla - Secondary axis of compound leaf.
• Rachis - The main axis of a pinnately compound leaf.
• Sheath - Any more or less tubular portion of the leaf surrounding the stem or culm, as in thePoaceae.
• Stipels - Paired scales, spines, or glands at the base of petiolule.
• Stipules - Paired scales, spines, glands, or blade-like structures at the base of a petiole.
