Plant tissue culture is a method of asexual reproduction used to produce clones of a plant with desirable traits. plant tissue culture relies on the fact that plant cells have the ability to regenerate a whole plant. single cells are dosed with certain chemicals that trigger dividing cells to produce roots, shoots, and leaves. which tenet of cell theory best serves as a basis for this type of biotechnology?

The answer is Cells come only from pre-existing cells.

There are three tenets of cell theory:
1. All living organisms are composed of one or more cells.
2. Cells are the basic structural and functional units in all living organisms.
3. Cells come only from pre-existing cells.

In plants tissue cultures, single cells divide to produce roots, shoots, and leaves. This division suggests there must be some pre-existing cells from which those organs will be produced. So, the tenet that cells come from other cells in cell division is a basis for plant tissue cultures.
