Question

Differentiation of blastomeres and morphogenetic movements in embryo can be seen during

Answer 1

Answer:

Differentiation of blastomeres and morphogenetic movements in embryos can be seen during the gastrulation stage.

Explanation:

• Gastrulation is the process in the early developmental stage during which the single-layered hollow sphere of cells, the blastula is transformed into a structure that is multi-layered, called the gastrula.
• It occurs after the cleavage stage and the blastula formation.
• The blastomeres are differentiated into three types of primary germ layers- ectoderm (outer), endoderm (inner), and mesoderm (middle).
• The movements which enable the transformation of the blastula into the gastrula are termed morphogenetic movements.
• The movement of cells from one place to another in the embryo which helps the reorganization of the blastula is known as a morphogenetic movement.
• The organogenesis process follows gastrulation.

Answer 2

Answer:

Differences in blastomers and morphogenetic movements in embryos can be observed during gastrulation.

Explanation:

Gastrulation is a process in the early stages of development in which an empty space with a single layer of cells, the blastula is converted into a multi-layered structure, called a gastrula.

It occurs after the stage of cracking and blastula formation.

Blastomers are divided into three types of primary viruses - ectoderm (external), endoderm (internal), and mesoderm (central).

Movements that allow the blastula to be transformed into a gastrula are called morphogenetic movements.

The movement of cells from one place to another in the embryo that facilitates blastula reconstruction is known as morphogenetic movement.

The process of organogenesis follows gastrulation.

Gastrulation is the initial stage of embryonic development of the animal, in which the blastula (an empty cell with a single layer of cells) is reorganized into a multi-layered structure known as the gastrula. Prior to gastrulation, the embryo is a continuous epithelial layer of cells; By the end of gastrulation, the embryo has begun to divide to form different cell lines, establish basic body axes (eg dorsal-ventral, anterior-posterior), and insert into one or more cell types including the intestinal tract. [1]

In animals with triploblastic, gastrula is trilaminar ("three-layer"). These three layers of bacteria are known as the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). [2] [3] In living organisms called diploblastic, such as Cnidaria and Ctenophora, gastrula contains only ectoderm and endoderm. These two layers are also sometimes called hypoblast and epiblast. [4] Sponges do not pass the gastrula stage, which is why they are the basal among all animals.

Gastrulation occurs after the rupture and formation of the blastula. Gastrulation is followed by organogenesis, in which individual organs grow between the newly formed viral layers. [5] Each layer creates certain tissues and organs in the developing embryo.
