Question

Who discovered Totipotency?

Answer 1

Hint: The ability of a cell to differentiate into distinct cell types is referred to as cell potency. The greater a cell's potency, the more cell types it can develop into. Potency is also defined as a cell's gene activation potential, which, like a continuum, starts with totipotency to denote a cell with the most differentiation potential, then progresses through pluripotency, multipotency, oligopotency, and unipotency.

Complete answer:
Gottlieb Haberlandt was the first to discover totipotency. He is credited as being the "Father of Plant Tissue Culture." He proposed that plant cells are totipotent, meaning they have the ability to produce the entire plant.
The ability of a single cell to proliferate and produce all of the differentiated cells in an organism is known as totipotency. Totipotent cells include spores and zygotes, for example.
The human development model can be used to describe the emergence of totipotent cells. When a sperm fertilises an egg, the fertilised egg produces a single totipotent cell called a zygote, which is the first step in human development.
This zygote divides into identical totipotent cells in the early hours after fertilisation, which can eventually develop into any of the three germ layers of a human (endoderm, mesoderm, or ectoderm), or placental cells (cytotrophoblast or syncytiotrophoblast).
The totipotent cells of the morula differentiate into cells that will eventually become either the blastocyst's Inner cell mass or the outer trophoblasts after reaching a 16-cell stage. These totipotent cells begin to specialise four days after conception and after numerous cycles of cell division. The inner cell mass, which contains embryonic stem cells, transforms into pluripotent cells.

Note:
The cell with the greatest differentiation potential, totipotency, can differentiate into any embryonic cell as well as extraembryonic cells, according to the spectrum of cell potency. Pluripotent cells, on the other hand, can only differentiate into embryonic cells.
