What happens after the formation of blastula and when the term layer is formed |
|
Answer» tion:The cells of the blastula form an epithelial (covering) layer, CALLED the BLASTODERM, enclosing a fluid-filled cavity, the blastocoel. After the blastula develops, it undergoes transition to the gastrula (q.v.), a process called gastrulation. In organisms such as mammals, the EARLIER morula (q.v.), a berrylike CLUSTER of cells, develops into a somewhat different form of blastula, the blastocyst (q.v.).i hope it will help you |
