Who discovered totipotency?

Answer

**Step-by-Step Text Solution:**

1. **Understanding Totipotency**: Totipotency refers to the ability of a single cell to divide and produce all the differentiated cells in an organism, including both the somatic and germ cells. This concept is crucial in developmental biology and plant propagation.

2. **Identifying the Scientist**: The scientist who first demonstrated the phenomenon of totipotency is known as Steward.

3. **Year of Discovery**: This discovery was made in the year 1964, when Steward conducted experiments using the phloem cells of carrot plants.

4. **Application of Totipotency**: The concept of totipotency is particularly significant in the field of plant biology, as it allows for the multiplication of rare and endangered plant species through a technique known as micropropagation.

5. **Conclusion**: Therefore, the answer to the question "Who discovered totipotency?" is that it was discovered by Steward in 1964 using carrot phloem cells.
