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 else can I help you with?
What is the blastocyst structure that becomes the embryo?
The inner cell mass of the blastocyst is the structure that becomes the embryo. It contains the cells that will develop into the fetus.
What is the main way that an embryo gets bigger?
The cells are known as stem cells meaning they can become any cell type. The embryo becomes bigger because certain genes in the DNA are activated allowing the cell to divide or produce certain determination factors that will make a stem cell become a neuron, muscle cell, etc.... The embryo grows in size as the stem cells divide repeatedly and then some of the stem cells become actual specific cells.
How do the cells in a blastocyst as it becomes an embryo?
Cells in a blastocyst start to differentiate into specific cell types, forming layers called the inner cell mass and the trophectoderm. These cells will give rise to different tissues and organs as the embryo develops. The inner cell mass forms the embryo itself, while the trophectoderm will become the placenta.
The cluster of developing cells from conception until birth is called an .?
Embryo, between the 3rd and 8th week. Fetus, after the 8th week
What is the first step of embryo screening?
The first step of embryo screening is typically to obtain a sample of cells from the developing embryo. This can be done through techniques such as biopsy or removing a few cells from the embryo for genetic analysis.
What is the blastocyst structure that becomes the embryo?
The inner cell mass of the blastocyst is the structure that becomes the embryo. It contains the cells that will develop into the fetus.
The cluster of developing cells from conception until birth is called what?
This cluster of cells change the baby grows from pre-embryo to embryo to fetus.
What happens to the embryo once stem cells are removed?
Once stem cells are removed from the embryo, the remaining embryo cannot develop into a fetus because the stem cells are essential for its growth and differentiation. The embryo is typically discarded after the stem cell extraction process.
What becomes the seeds when sperm cells fertilize the egg cells?
When sperm cells fertilize egg cells, the resulting fused cell is called a zygote. The zygote then undergoes cell division and differentiation to form an embryo. Ultimately, the embryo develops into an organism.

What happens to an embryo when stem cells are harvested from it?
the embryo is killed
Are more stem cells found in an embryo or an adult?
There are more cells found in an embryo than an adult.
The cluster of developing cells from conception until birth is called an .?
Embryo, between the 3rd and 8th week. Fetus, after the 8th week

What is the relationship between the number of cells within an embryo sac and the number of nuclei within the embryo sac?
The number of cells within an embryo sac is typically equal to the number of nuclei within the embryo sac. This is because each cell of the embryo sac contains one nucleus, and during the process of embryo sac development, the number of cells and nuclei increase concurrently.
What color is the embryo?
The precise color of an embryo will change as it develops, but for much of development, pigmented cells have not yet formed, so the embryo will mostly be white-pink in color. The embryo proper will be white or off-white, but the circulatory system forms pretty early so the red of the blood moving through the embryo gives it a pinkish hue.
