The fluid-filled bag of thin tissue that develops around the embryo is called the amniotic sac. It helps protect and cushion the developing embryo/fetus during pregnancy.
Placenta is the organ that is made from both tissue of the embryo and the mother. It forms during pregnancy for nutrient and waste exchange between the mother and fetus.
The number of tissue layers that develop in the embryo is typically three. These three primary germ layers are the ectoderm, mesoderm, and endoderm. Each layer gives rise to specific tissues and structures in the developing organism.
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.
The envelope of thin tissue that surrounds the developing embryo is called the amniotic sac. It is filled with amniotic fluid, providing protection and cushioning for the developing fetus during pregnancy.

Cartilage
The first connective tissue in the embryo is called mesenchyme. Mesenchyme is a type of embryonic tissue that gives rise to various connective tissues in the body, such as bone, cartilage, and muscle. It also plays a role in the development of organs and blood vessels.

It is made up of mostly hyaline cartilage.
