Auxin has an effect on plant embryos much like the Bicoid protein in Drosophila.If auxin were added to a culture of embryonic root cells,what would be the likely result?
A)Root cells would elongate and mature.
B)Root cells would change into meristem cells.
C)Root cells would halt their development.
D)Root cells would not respond to auxin.

Question

Quizplus · Accepted Answer

Auxin promotes cell elongation and differentiation, so the addition of auxin to a culture of embryonic root cells would likely result in the root cells elongating and maturing. Choice B is incorrect because auxin would promote the differentiation of root cells into specific cell types, rather than causing them to revert to meristem cells. Choice C is incorrect because auxin promotes development, not halting it. Choice D is unlikely because root cells generally respond to auxin.
