By 2 weeks after fertilization the morula has implanted into the uterine lining and transforms into a(n) . this time is when the , or the organ that will provide nourishment to the fetus by exchanging nutrients and waste products, begins to develop.

Placenta

Explanation:

The term morula is given to the first stage of embryonic development of animals. This stage corresponds to a mass of cells (from 16 to 64 cells) called blastomers. This stage of development is called this because its shape resembles blackberry fruit. The cells present inside the morula are still undifferentiated, that is, they can transform into any type of cell in the organism. Usually two weeks after fertilization, the morula implanted in the uterine lining and turned into a placenta.

The shape of the morula will depend on how these cleavages occur. And the cleavages depend on the amount and position of the calf stored in the egg. Attention: Some authors consider that animals that have a lot of calf in their eggs do not form morules, moving on to the next direct embryonic stage - the blastula.
