stemA term of art used in clinical trials for a prompt, question or instruction in a patient-reported outcome item.
stemthe part of the shoot of vascular plants from which are produced leaves at regular intervals (NODES) and reproductive structures. Stems are usually circular in cross section but some are square (for example, members of the family Labiatae, such as mint and lavender) while others are ribbed. The internal structure of stems can be herbaceous (non-woody) or show SECONDARY THICKENING. See Fig. 289 .
The forms adopted by stems are highly varied, ranging from the oak tree to climbing plants such as Clematis and the pea. Stems are sometimes used as underground storage organs as in RHIZOMES, CORMS, BULBS (underground shoots with food stored in fleshy leaves) and stem TUBERS, e.g. potato, while others, such as the strawberry RUNNER and suckers of mint, are adapted for VEGETATIVE PROPAGATION.
