What are the key differences between a blastocyte and a blastocyst in embryonic development?

A blastocyst is a more advanced stage of development compared to a blastocyte. The key differences lie in their structure and function. A blastocyte is an early stage of development with a single layer of cells, while a blastocyst has multiple layers of cells and a fluid-filled cavity. Additionally, a blastocyst is capable of implanting into the uterus and developing further, whereas a blastocyte is not.
