AI Thread Summary
Totipotency refers to the ability of a stem cell to differentiate into any type of cell, allowing a single isolated plant cell to develop into an entire plant. This concept is also applicable in humans, where a fertilized egg is considered totipotent. The discussion highlights the distinction between totipotency, pluripotency (which allows for more restricted differentiation), and unipotency (which permits differentiation into only one cell type). The topic emphasizes the significance of these capabilities in plant tissues and their broader implications in biology. Additionally, a recent presentation on stem cells, differentiation, and reprogramming was shared for further exploration of the subject.

What Is Meant By Totipotency (in Relation To Plant Tisssues)
 
Biology news on Phys.org
A (stem) cell has the potential to give rise to all cell lineages.
 
A demonstrated capability in plants where a single, isolated cell can develop into a whole plant.
 
In humans too, a fertilized egg is totipotent. As said, it is the capacity to differentiate into any type of tissue. Then there is also pluripotency (more restricted differentiation paths) and unipotency (just one differentiation path).

For those interested, just a few weeks ago I gave a presentation on stemcells/differentiation/reprogramming: http://home.student.uva.nl/monique.vandervoet/MV_regenerationSCs.ppt
