What is yeast? Describe the process of reproduction in yeast with the help of labelled diagrams.
Yeast is a non-green plant (fungus). It reproduces by budding. In yeast, a bud first appears outside its cell wall. Immediately the parent nucleus divides itself into two in such a way that one of its parts moves into the bud. Then the bud detaches itself from the parent cell to form a new yeast cell.
