What is the reason of formation of embryoid from pollen grain in tissue culture medium
Cellular totipotency
Organogenesis
Double fertilization
Test tube culture
The Correct Option is A
Solution and Explanation
A mass of tissue created during culture is called an embryoid. Cellular totipotency is what causes pollen in tissue culture media to develop into an embryo. A cell's capacity to differentiate into distinct cell types is known as cell potency. A cell's potency increases with the number of various cell types it may differentiate into.

Tissue Culture
Tissue culture, also known as cell culture, is a technique in which living cells are grown in a laboratory environment under controlled conditions. Tissue culture is commonly used in the field of biotechnology and medical research to study the behavior of cells in vitro (outside of their natural environment) and to produce large quantities of cells for research or commercial purposes.
The process of tissue culture involves taking a small sample of tissue or cells from an organism and placing them in a sterile container containing a nutrient-rich medium that provides the necessary nutrients for the cells to grow and divide. The culture is then placed in an incubator at a specific temperature and humidity level to provide optimal growth conditions for the cells.
Tissue culture has a wide range of applications, including the production of vaccines, the study of cellular physiology and biochemistry, the development of new drugs, and the production of genetically modified organisms. In addition, tissue culture has been used to produce artificial organs for transplantation and to study the behavior of cancer cells.
Although tissue culture has revolutionized the field of biological research, it also has its limitations. Cells grown in tissue culture may not behave the same way as cells in their natural environment, and the process of culturing cells can introduce mutations or other changes in the cells that may affect their behavior. Therefore, caution must be exercised when interpreting results obtained from tissue culture experiments.
