Answer:
The correct answer is - regenerative cells.
Step-by-step explanation:
Yeast is the unicellular organism that reproduce by the process of the asexual reproduction specifically budding. Budding is the mode of asexual reproduction in which a outgrowth or bud develop at a specific part of the cell and cell division take place.
It is also seen in multi cellular organisms like hydra, sponge and others. In hydra a outgrowth develop at a specific point of the body and divide and grow an individual ultimately detaches to the main body. It iis occur due to the regenerative cells that goes in cell divisions.
Thus, the correct answer is - regenerative cells.
