Who started plant tissue culture technique?

Explanation

**Step-by-Step Solution:**

1. **Understanding Plant Tissue Culture**: Plant tissue culture is a technique used to grow plant cells, tissues, or organs in a controlled environment, typically on a nutrient medium. This method allows for the cloning of plants and the production of multiple progeny from a single cell.

2. **Key Concept - Totipotency**: The ability of a single plant cell to develop into a whole organism is known as totipotency. This property is fundamental to the success of plant tissue culture, as it allows for the regeneration of entire plants from individual cells.

3. **Historical Development**: The development of plant tissue culture techniques began in the 18th century but gained significant traction after 1898.
