Process: budding. Activity: dissolve about $10$ g of sugar in $100$ mL of water, take $20$ mL of this solution in a test tube and add a pinch of yeast granules. Put a cotton plug on the mouth of the test tube and keep it in a warm place. After $1$ to $2$ hours, put a small drop of the yeast culture on a slide, cover it with a coverslip and observe it under a microscope: many yeast cells show small outgrowths (buds), and some buds carry buds of their own. Another organism that reproduces by budding: Hydra.
