What is the fertilized egg after 3 cell layers develop called?
After three cell layers develop, the fertilized egg is called a gastrula. During this stage, the three primary germ layers—ectoderm, mesoderm, and endoderm—form, which will eventually give rise to different tissues and organs in the developing organism. This process is part of embryonic development and is critical for proper organ formation.
Is blastulation and gastrulation one and the same thing?
No, blastulation and gastrulation are distinct processes in embryonic development. Blastulation is the formation of the blastula from the zygote, while gastrulation is the process during which the three germ layers (ectoderm, mesoderm, and endoderm) are formed from the blastula.
What is the process involving cell rearrangements to form the three primary germ layers?
During gastrulation in embryonic development, cells undergo rearrangements to form the three primary germ layers (ectoderm, mesoderm, endoderm). This process involves invagination, ingression, and delamination of cells. Invagination occurs when cells move inward, ingression refers to individual cells leaving the surface epithelium and entering the interior, and delamination involves cells moving between epithelial layers. Together, these movements help establish the three germ layers that give rise to different tissues and organs in the developing embryo.
What term refers to the process in which cells differentiate into layers with each layer ultimately forming distinct parts of the fetus?
Gastrulation is the term that refers to the process in which cells differentiate into layers, with each layer ultimately forming distinct parts of the fetus. During gastrulation, the three primary germ layers (ectoderm, mesoderm, and endoderm) are established in early embryonic development.
What is triple fusion?
Triple fusion is a process in plants where three individual nuclei from the male gamete (pollen) join together with two nuclei in the female gamete (ovule) during fertilization. This results in the formation of a triploid cell which eventually develops into the endosperm of the seed, providing essential nutrients for the growing embryo.

What are the three primary periods in tooth formation?
The process of tooth formation, called odontogenesis, is divided into three primary periods: growth, calcification, and eruption.
What are the four stages after fertilization?
The four stages following fertilization are cleavage, blastula formation, gastrulation, and organogenesis. Cleavage is the rapid cell division of the zygote, leading to the formation of the blastula, which is a hollow ball of cells. Gastrulation involves cell movement and rearrangement to form the three germ layers: endoderm, mesoderm, and ectoderm. Organogenesis is the process of organ formation from the germ layers.
How do the cells in a blastyst change as it becomes an embryo?
During development, the blastula undergoes a process called gastrulation, in which the cells rearrange and differentiate into the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to all the tissues and organs in the embryo. This process is essential for the formation of a complex, multicellular organism from a simple, single-celled embryo.

What is an aziridine?
An aziridination is a reaction which results in the formation of an aziridine.
What is the process that results in folding the blastocyst?
The folding of the blastocyst is driven by differential growth of the cells in the embryo, specifically the epiblast and hypoblast layers. As the cells proliferate and divide unequally, they cause a physical force that pushes the epiblast towards the inside of the embryo, initiating the folding process. This folding is crucial for establishing the three germ layers - endoderm, mesoderm, and ectoderm, which give rise to all tissues and organs in the body.
Humans have eyes composed of three layers?
The three layers are the retina, sclera, and the choroid.
