Question

This image is of a human embryo. It took many weeks of development to get to this stage. Prior to this, all of the human cells were not differentiated, and the organism would have simply looked like a grouping of all the same type of cells. What is the name given to the type of cells in humans that are not differentiated?

Answer 1

The embryo develops inside an organ called the uterus (womb). It sinks into the soft lining of the uterus and absorbs food from the mother through an organ called the placenta, which develops from the embryo. The uterus has a very stretchy wall so that it can expand as the baby grows.
