How does a pluripotent cell differ from a totipotent cell?

Cell potency is referred to as the ability of cells to give rise to give rise to different or number of cell types. More the potency of cell more well it could differentiate into different types of cells. Cell potency is of three basic types; multi-potent, totipotent, pluripotent.

Totipotent cells can be differentiated into any types of cells including embryonic and non-embryonic cells like placenta.

e.g. zygote

Pluripotent cells can differentiate to any type of cells but not the placenta cells.

e.g. embryonic stem cells

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
