Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species. Roots While roots are most often found underground, this is not universally the case. Aerial roots are any roots that emerge aboveground. Epiphytic plants, such as orchids, can live their entire lives without touching soil. Other types of aerial roots, such as those of the strangler fig or banyan, germinate...

Dorsal Root Ganglia Neurons and Differentiated Adipose-derived Stem Cells: An In Vitro Co-culture Model to Study Peripheral Nerve Regeneration

Dorsal root ganglia (DRG) are structures containing the sensory neurons of the peripheral nervous system. When dissociated, they can be co-cultured with SC-like adipose-derived stem cells (ASC), providing a valuable model to study in vitro nerve regeneration and myelination, mimicking the in vivo environment at the injury site.

Source: Harris, S. L., et al. Monitoring Bacterial Colonization and Maintenance on Arabidopsis thaliana Roots in a Floating Hydroponic System. J. Vis. Exp. (2019)This video demonstrates a protocol for monitoring the colonization of root-associated bacteria on Arabidopsis thaliana seedlings grown in a soilless system. Following colonization, bacteria are dislodged by sonication, then diluted, plated, and incubated to form colonies that reflect bacterial attachment and viability.

Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.
FAQs
Elongation changes reflect coordinated cell division and cell expansion, rather than a single geometric event. Division contributes new cells, while expansion increases their size along the organ axis. Consequently, a measured difference in length can indicate altered growth behavior at the seedling level, although the metric itself reports the integrated longitudinal outcome rather than separating those cellular contributions.
Physics-oriented analyses treat the two lengths as spatial variables that can be compared across seedlings or environmental conditions. Those comparisons help quantify changes in geometry and growth response, while also supplying dimensions for models of plant structure. In this context, the measurements connect biological development with questions about transport, mechanical stability, and resource acquisition.
Curvature and branching complicate a single straight-line measurement because the root does not follow one simple axis. Imaging or tracing provides a way to represent the organ’s course from its defined base toward its tip. This preserves spatial information needed for reliable comparisons of root architecture and avoids reducing a complex form to an ambiguous endpoint distance.
Measuring stems and roots as separate quantities retains information about organ-specific architecture. A seedling could show one pattern of longitudinal growth in its stem and another in its root, and a combined or unlabeled value would hide that contrast. Separate records therefore support clearer comparisons of structure, growth, and environmental responses.
A consistent workflow begins by specifying the base and tip for each organ, then measuring the longitudinal extent between those points. Stem measurements can be recorded directly when the axis is clear; curved or branched roots may require imaging or tracing. Applying the same endpoint rules across samples makes the resulting comparisons more interpretable.
Researchers can use these measurements in phenotyping and controlled growth experiments to compare seedling architecture or evaluate responses to environmental conditions. The resulting values also serve as inputs to models linking plant geometry with transport, stability, and resource acquisition. Their main outcome is a quantitative basis for comparing structural growth rather than a complete explanation of its cause.
