The fact that plants can be cloned from somatic cells demonstrates that all cells in a plant contain the complete genetic blueprint for the organism.

Here's why:

* Somatic cells are any cells in a multicellular organism that are not involved in sexual reproduction (i.e., not gametes).

* Cloning from somatic cells means that a new plant can be grown from a cell that is not a reproductive cell.

* This proves that the somatic cell contains all the necessary genetic information to develop into a complete organism, just like a zygote (the fertilized egg).

This principle contrasts with the situation in animals, where most somatic cells are specialized and lack the full genetic potential for development.
