Question
Explain budding in yeast.
✓
Answer
(i) Budding is a method of asexual reproduction in a unicellular fungus-yeast.
(ii) Yeast cell produces two daughter nuclei by mitotic division. This yeast cell is called as parent cell.
(iii) A small bulge appears on the surface of parent cell which is the bud.
(iv) One of the two daughter nuclei enters this bud.
(v) After sufficient growth, bud separates from the parent cell and starts to live independently, as a daughter yeast cell.
