Gastrula!!!!
Gastrula.
Pharyngeal slits are openings through which water is taken into the pharynx, or throat.

The blastula is an embryonic structure that is formed from one cell layer. This later forms the three cell layered gastrula. All of the layers of the organism are formed from these three layers. See the link below:
Different plants use different methods. Some use fruit, some use seeds whose shape makes it easy for them to be carried by wind, some seeds develop burrs with which they stick to passing animals and then drop to the ground later.
The Davson-Danielli model proposed that the phospholipid bilayer was put between two layers of globular protein, hoping to understand the surface tension of the bilayer. The fluid mosaic model then expanded on this by including proteins that could cross the membrane, without needing the extra protein layers.

Mesoderm
The only one that will develop into different structures is the zygote. After that it will divide into 4, then 8, etc. But each of those will not develop in to all body parts. By that time differentiation has begun.

Cleavage - the repeated cell division of the zygote to create a blastula.Gastrulation - the formation of distinct layers which later give rise to different structures.

The middle layer is formed during the gastrulation. This layer develops into muscles, bones and blood vessels.
About ten you start to develop some start earlier some later
