Question

Cellular totipotency was demonstrated by
A. Theodore Schwann
B. A.V. Leeuwenhoek
C. F. C. Steward
D. Robert Hooke

Answer 1

Hint: Cellular totipotency is described as the inherent potential of a cell to give rise to a whole body. Cell totipotency is defined as the ability of a cell that is able to generate new organisms as their parental one. In the tissue plant culture, a somatic tissue called the explants is used to produce the new tissue. The produced tissues are responsible for generating the whole plant through the cell totipotency process, making the cells able to divide and differentiate.

Complete step by step answer: From the given options, cellular totipotency was demonstrated by F. C. Steward. Frederick Campion Steward was a British botanist. He demonstrated that plant cells are totipotent that carry the genetic information to develop into complete plants.
Thus, the correct option is (C). F.C. Steward.

Additional Information: A cell's ability to grow and develop into a multicellular organism is known as cellular totipotency. All the organisms are formed from a zygote. On the contrary, a differentiated cell's ability to transform into a totipotent cell is known as differentiation. All the plant cells have the ability to form an adult plant.
On the other side, animal cells possess irreversible differentiation, and this differentiated cell never resumes totipotency. In the case of bacteria, it divides and produces a new bacterial cell. This also states that bacterial cells are also totipotent.

Note: A German Botanist established the concept of totipotency in 1902. He demonstrates that every living cell of the plant body can form a new plant body because it is derived from the fertilized egg. The fertilized egg is known as a zygote that contains genetic information.
