Contrast the structure of a blastula with that of a gastrula?
Blastula is a hollow structure, that consists of a single layer of morphologically distinct cells, trophoblasts, forming the periphery of sphere. The space enclosed within trophoblast layer is filled with a fluid called as blastoceol. At one end of blastula, there is a cluster of undifferentiated cells, known as inner cell mass. During the gastrula stage the inner cell mass began to align in a plane (like a disk) giving rise to three distinct germ layers from which the future organs will develop.
Compare the frogs blastula with that of a sea star?
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.
Outline the path of development in animal from gametes to embryos?
The development of an animal from gametes to embryos begins with fertilization, where a sperm cell merges with an egg cell to form a zygote. This zygote undergoes a series of mitotic divisions known as cleavage, leading to the formation of a multicellular blastula. Following this, the process of gastrulation occurs, where the blastula reorganizes into a three-layered structure called the gastrula, laying the foundation for the future development of tissues and organs. This progression from zygote to blastula to gastrula marks the critical transition from a single-celled organism to a multi-cellular embryo.
What are the layers in the gastrula?
The three primary germ layers in the gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). Each layer gives rise to different tissues and organs in the developing embryo.
How is a blastula different from a gastrula?

What is the correct order of developmental sequence - Fertilization blastula gastrula adult zygote cleavage embryo meosis?
The correct order of developmental sequence is: Fertilization -> Zygote -> Cleavage -> Blastula -> Gastrula -> Embryo -> Meiosis -> Adult.
What is the relationship between gastrula and blastula?
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:

What factor causes a frog's morula blastula and gastrula to look different than those of a sea star?
Distribution of yolk cells.

What is the stage all three germ layers of tissue are evident?
The stage when all three germ layers (ectoderm, mesoderm, and endoderm) are evident is called the gastrula stage. During gastrulation, the blastula undergoes a series of cell movements and differentiations to form the three germ layers that will give rise to all the specialized tissues and organs in the body.
What blastocyst produce the primordial germ cell?
Gastrula (early gastrula follow the blastula in the development sequence) ~ As a result of gastrulation, a three-layered embryo forms, each layer corresponding to a primary germ layer from which all body tissues develop.
Do all animals have a blastula?
yes they have a blastula.
