If a stem cell divides asymmetrically, produce two types of cells (a stem cell & a developmentally committed cell) are produced at each division, is called the single stem cell asymmetry.

The potency of a cell is an intrinsic property and is greater than or equal to its fate. Potency is described as the gene activation potential within a cell which begins with – 

Totipotency, Pluripotency, Multipotency  and finally Unipotency.

Totipotency

the ability of a single cell to divide and produce all of the differentiated cells in an organism (embryonic and extra embryonic cells).

Eg- spores and zygotes

Pluripotency A stem cell that has the potential to differentiate into any of three germ layers(endoderm , mesoderm & ectoderm). Eg-all embryonic cells
