1) How is a Gastrula different from the Blastula?
1) How is a Gastrula different from the Blastula?
The blastula is the developmental stage that forms before the gastrula. During embryonic development, the blastula undergoes a process called gastrulation, which results in the formation of the gastrula.
The frog blastula is formed through holoblastic cleavage, resulting in a multicellular blastula with a fluid-filled cavity (blastocoel). In contrast, the sea star blastula is formed through radial holoblastic cleavage, leading to a solid blastula with no blastocoel. Additionally, the frog blastula undergoes gastrulation to form a gastrula with three germ layers, while the sea star blastula directly develops into a bipinnaria larva without gastrulation.
The Whitefish blastula is a fish so it belongs in the Animal kingdom.
A blastocoele is the fluid-filled cavity in the blastula.
