Why plants can regenerate
See it
Plant regeneration is possible because plant cells and tissues can retain remarkable developmental plasticity. The historical idea of totipotency helped motivate tissue-culture research, while modern work shows that regeneration depends on cell state, tissue competence, signals, and developmental context rather than a simplistic promise that every cell will regenerate a whole plant.
Understand it
Avoid saying “every plant cell can always become a whole plant.” That overstates the biology.
Try it
Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
