Experiments on selective adhesion between ectoderm, mesoderm, and endoderm derived from amphibian embryos demonstrated that ____.
A) ectoderm cells have positive affinity for mesoderm cells, but negative affinity for endoderm cells
B) ectoderm cells have negative affinity for mesoderm cells, but positive affinity for endoderm cells
C) mesoderm cells have negative affinity for endoderm and ectoderm cells
D) ectoderm cells have positive affinity for both endoderm and mesoderm cells
E) endoderm cells have positive affinity for both ectoderm and mesoderm cells

Question

Quizplus · Accepted Answer

EExperiments on selective adhesion between the three germ layers derived from amphibian embryos have shown that ectoderm cells have a positive affinity for mesoderm cells but not for endoderm cells, indicating a selective adhesion pattern. Similarly, endoderm cells exhibit positive affinity for both ectoderm and mesoderm cells, suggesting a mutual attraction that facilitates the organization and differentiation of tissues during embryonic development.
