As nouns the difference between blastula and gastrulation

is that blastula is (embryology) an early form in the development of an embryo, consisting of a spherical layer of cells filled with fluid; a blastosphere while gastrulation is (embryology|biology) the stage of embryo development at which a gastrula is formed from the blastula by the inward migration of cells.

Gastrulation is a coordinate term of morulation.

As nouns the difference between morulation and gastrulation

is that morulation is the cleavage or segmentation of the ovum by which a morula is formed while gastrulation is the stage of embryo development at which a gastrula is formed from the blastula by the inward migration of cells.

Organogenesis is a coordinate term of gastrulation.

As nouns the difference between organogenesis and gastrulation

is that organogenesis is (biology) the formation and development of the organs of an organism from embryonic cells while gastrulation is (embryology|biology) the stage of embryo development at which a gastrula is formed from the blastula by the inward migration of cells.

As nouns the difference between tissue and hypoblast

is that tissue is thin, woven, gauze-like fabric while hypoblast is (embryology) a type of tissue that forms from the inner cell mass and later is incorporated into the endoderm.

As a verb tissue

is to form tissue of; to interweave.

As nouns the difference between endoderm and hypoblast

is that endoderm is one of the three tissue layers in the embryo of a metazoan animal through development, it will produce the digestive system of the adult while hypoblast is (embryology) a type of tissue that forms from the inner cell mass and later is incorporated into the endoderm.

Hypoblast is a related term of embryoblast.

As nouns the difference between embryoblast and hypoblast

is that embryoblast is a mass of cells at the embryonic pole of the blastocyst, that develops to form the embryo while hypoblast is a type of tissue that forms from the inner cell mass and later is incorporated into the endoderm.

Epiblast is a related term of hypoblast.

As nouns the difference between epiblast and hypoblast

is that epiblast is (biology) the outer layer of a blastula that, after gastrulation, becomes the ectoderm while hypoblast is (embryology) a type of tissue that forms from the inner cell mass and later is incorporated into the endoderm.

As nouns the difference between potentiality and ingression

is that potentiality is the quality of being, or having potential while ingression is the act or process of entering or intruding.

As nouns the difference between actuality and ingression

is that actuality is the state of existing; existence while ingression is the act or process of entering or intruding.

As nouns the difference between blastula and ingression

is that blastula is (embryology) an early form in the development of an embryo, consisting of a spherical layer of cells filled with fluid; a blastosphere while ingression is the act or process of entering or intruding.
