The division of a bacterial cell into two daughter cells(called binary fission) is accomplished by a protein ftsz is very similar to the tubulin subunits that form microtubules in eukaryotes. after the replicated bacterial chromosomes have moved to opposite ends of the cell, a ring of ftsz proteins forms inside the plasma membrane in the region where the cell will divide. as the ftsz ring constricts, the plasma membrane and bacterial cell wall fold in eventually separate into two daughter cells.
plant and animal cells also require cytoskeleton proteins for cytokinesis, although the roles these proteins play differ among bacteria, plants, and animals.
for each of the following, determine if the statement is true or false for each group of organisms:

1. cells divide by constriction of a ring of protein
2. the presence of a cell wall prevents the cell from diving by constriction
3. tubulin or tubulin-molecules function in binary fission(in bacteria) or cytokinesis(in animals and plants)
