Which statement about pattern formation in an embryo is true?
A) It is a process found in animal embryos but not in plant embryos.
B) It involves the French flag protein.
C) It is a pattern imposed on cells after they differentiate.
D) It can involve programmed cell death.
E) It involves transcription factors but does not involve inducers.

Question

Quizplus · Accepted Answer

Pattern formation in an embryo can involve programmed cell death, also known as apoptosis. This process can help shape and refine developing tissues and organs. Choices A, B, and E are incorrect as pattern formation is also observed in plant embryos, the French flag model is one model of pattern formation but not the only one, and induction of cell differentiation by signals (inducers) is a key part of pattern formation. Choice C is incorrect as pattern formation is a process that occurs before differentiation.
