Question

Quizplus · Accepted Answer

The embryonic stage begins after implantation of the fertilized egg in the uterus and continues until the completion of organogenesis, which is the development of the major organs and body systems. Option A is incorrect because mitosis and meiosis occur throughout embryonic development. Option C is incorrect because meiosis occurs during gametogenesis, not embryonic development. Option D is incorrect because germination applies to plant development, not embryonic development. Option E is incorrect because conception refers to the fertilization of the egg by the sperm, which occurs before the embryonic stage begins.
