what is the difference between inderterminate and determinate cleavage?

kaplan's explanation seems to be vague to be. Can anyone point out the key differences. Thanks

Determinate cleavage=protostomes

Indeterminate cleavage=deuterostomes(us). radially cleave perpendicular to polar axis. cells fate is not determined early on.

amsie's right (as usual). Indeterminate cleavage in deuterostomes includes the first 4 cleavages, I think, where the zygote progesses to 16 cells. Any one of these cells can be taken away and an entirely new organism can be produced. (This is where identical twins come from, kids!)

As a side note, this is where much of the new hype about being able to clone without destroying the embryo is coming from. Interview topic?

thanks lo, but what is the difference between protostomes and deuterostomes? are they another term for determine and inderterminate cleavage...?

You will learn a lot more by searching on your own rather than having people tell you the answers. Just my opinion.

oy vey. *NO* they are not the same as determinate/indeterminate!



Deuterostomes: blastopore becomes anus. Ex: us, starfish, birds.Radial cleavage of cells that is INDETERMINATE(fate is not determined till later)

Protostomes:blastopore becomes mouth. Ex:flatworms, mollusks,arthopods,annelids. Spiral cleavage of cells that is DETERMINATE(fate of cell determined as its formed)

Well I guess we finally answered that 2-celled embryo question that's been causing a lot of controversy in the past week, & hopefully the question about forming a new frog from a tadpole's tail, heh!
