Human stem cells can become any kind of human cell, plant stem cells can only become root cells or leaf cells.
|
|
|
Human stem cells can only become neurones or kidney cells, whereas plant stem cells can become any kind of cell.

|
|
Once plant cells have differentiated into specialised cells, they can re-differentiate into another type of specialised cell if needed.

|
Once human cells have differentiated, they mutate to give you special powers, like x-ray vision!

Detailed explanation-1: -That said, unlike human stem cells, the growth factors, cytokines and other proteins, which are the products of plant stem cells, do not have the ability to act in the same way in humans, as in plants. Plant stem cells communicate in a different biochemical “language” that human cells do not recognize.
Detailed explanation-2: -They are unspecialized: Specialized cells have specific capabilities that allow them to perform certain tasks. For example a red blood cell contains hemoglobin that allows it to carry oxygen. Stem cells have unspecialized capability and do not have tissue-specific structures to perform specialized functions.
Detailed explanation-3: -Plant stem cells do not undergo the process of ageing and senescence, they undergo differentiation to form specialized and unspecialized cells. These in turn have the potential to develop into any organ or tissue. Therefore, plant stem cells are termed as totipotent cells.
