In both animals and plants, undifferentiated cells go through a process of maturation that begins when they become committed to a specific cell lineage, progresses through a stage of cell fate determination for a specific cell type, and ends in differentiation as cells acquire the gene expression pattern characteristic of a specific cell type. Below certain statement are made regarding this.

A. In autonomous specification, the cell “knows” very early what it is to become without interacting with other cells.

B. Conditional specification is the process by which cells achieve their respective fates by interacting with other cells. 

C. If cells from one region of a vertebrate blastula that have been fate mapped to give rise to dorsal tissues are transplanted into the presumptive ventral region of another embryo, the transplanted “donor” cells will change their fates and develop into ventral cell types.

D. Even in the very early cleavage stages of the snail Patella, blastomeres that are presumptive trochoblast cells can be isolated in a petri dish. There, they do not develop  into the same ciliated cell types that they would give rise to in the embryo and with the same temporal precision.
