Slide 6 – Mitosis (interphase)
Slide 7 – Formation of the blastomere
Slide 8 - Blastula
Slide 9 - Morphogenesis
Slide 10 - Gastulation
Slide 11 – Blastopore and Archenteron
Slide 12 - Neurulation
Slide 13 – Radial and spiral cleavage
Slide 14 – Cleavage patterns
Slide 15 – Protostome and deuterostome body plan
Slide 16 – Protosomes - schizocoelom
The blastopore is the single opening of the archenteron and in protosomes, the blastopore forms the mouth.
The development of the mesoderm in protosomes are called schizocoelom which is defined as the developing mesoderm rises from the area near the blastophore where division takes place forming the mesoderm
Slide 17 – Deuterostomes - enterocoelom
In deuterosomes, the blastopore (single opening of the archenteron) forms the anus.
The development of the mesoderm is called an enterocoelom which is defined as the developing mesoderm rises from a pair of mesodermal pouch from the primitive gut (endoderm). This pouch enlarges until they meet and fuse
