Question

What would you call the parenchyma cells that are made to divide under controlled laboratory conditions during plant tissue culture?

Answer 1

1: Introduction to dedifferentiation
It is the phenomenon in which a differentiated cell loses specialisation and regains the ability of division under certain signals. Example: Fully differentiated permanent parenchymatous cells get dedifferentiated into meristematic cells and form interfascicular cambium.

2: Plant tissue culture
It is a technique to grow plant tissues or organs in a culture medium under sterile conditions.

3: Parenchyma cells in tissue culture
The parenchyma cells that get dedifferentiated and regain their ability of division lead to callus formation.
