The embryonic stage in which cell migration and differentiation occurs is known as a?
The embryonic stage in which cell migration and differentiation occurs is known as gastrulation. During this process, cells undergo extensive reorganization to form the three germ layers - ectoderm, mesoderm, and endoderm, which give rise to various tissues and organs in the developing embryo.
The process by which a white blood cell ingests a disease causing organism?
The process by which a white blood cell ingests a disease-causing organism is called phagocytosis. The white blood cell engulfs the pathogen using its cell membrane, forming a vesicle called a phagosome. The phagosome then fuses with a lysosome to form a phagolysosome, where the pathogen is destroyed.
What are the techniques to produce embryonic stem cells and embryonic germ cells?
Embryonic stem cells are typically derived from the inner cell mass of a blastocyst, a very early stage of embryonic development. This involves in vitro fertilization of an egg cell with sperm to form a zygote, which then develops into a blastocyst. Embryonic germ cells are derived from primordial germ cells found in the embryo. Techniques for producing these cells involve careful manipulation of embryonic development and culture conditions to isolate and maintain these specific cell types.
Is a human blood cell made up of smaller cells?
No, a human blood cell is not made up of smaller cells. It is a type of cell called a red blood cell, which lacks a nucleus and most organelles, making it unable to divide and form smaller cells. Each red blood cell is a single, unique cell that carries oxygen to tissues and removes carbon dioxide.
During embryonic development of animals tissue layers form This process of embryonic tissue development is called?
The process of embryonic tissue development where tissue layers form during animal development is called gastrulation. This process involves the rearrangement and differentiation of cells to create distinct layers that will give rise to different body structures and organs.
