Question

Development of dicot embryo biology discussion

Answer 1

After fertilization, the fertilized egg is called zygote or oospore which develops into an embryo. The oospore before it actually enters into the process undergoes a period of rest which may vary from few hours to few months. Generally the zygote (oospore) divides immediately after the first division of the primary endosperm nucleus.

Unlike gymnosperms where the early stages of the development show free nuclear divisions the first division of zygote is always followed by wall-formation resulting in a two-celled pro-embryo. Practically there are no fundamental differences in the early stages of the development of the embryos of monocots and dicots
