In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
The skeleton of an embryo is originally made of cartilage, a flexible tissue that later undergoes ossification to become bone. During development, the cartilage is replaced by bone in a process known as endochondral ossification.
Um, I think it is...Cartilage?
Well bones in an embryo aren't really there yet until the embryo becomes multi cellular and more of a child. Even when the embryo becomes more complex the bones are still just cartilage the same material that makes up your nose. Over time a bone cell called osteoblast applies both calcium and phosphate thus the bones become more dense hope i answered your question
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.
Many of the bones were made in the form of cartillage that then ossified (turned to bone). Other bones were formed from membranes, most notable the skull. The methods of formation are called endochondrial and intramembranous developement respectively.Before your birth your skeleton were not formed, calcium leads to the formation of the bone of your skeleton.

It is made up of mostly hyaline cartilage.
