Budding

Abstract

Budding is a form of asexual reproduction utilized by unicellular fungi known as yeast. A small protuberance is formed on the cell wall that grows in size until it is almost the size of the original yeast cell, forming a narrow neck between the two cells. Cytokinesis then occurs at the neck between the two cells.

Keywords: budding; yeast; fungi; asexual reproduction; dimorphism
