Question

The addition of yeast into bread dough makes it raised by increasing its volume, and the growth of fungus takes place on bread slice when it is left for a longer time in moisture. A researcher took samples from the dough of bread on slide A, and from old bread on slide B. The researcher observed the growth of these organisms under the microscope. What type of asexual reproduction might have been observed by the researcher on both the slides? *
(a) Slide A- Budding, Slide B-Spore Formation
(b)Slide A- Spore formation, Slide B-Budding
(c) Slide A- Budding, Slide B-Fragmentation
(d)Slide A- Fragmentation, Slide B-Spore Formation

Answer 1

Explanation:

In bread making (or special yeasted cakes), the yeast organisms expel carbon dioxide as they feed off of sugars. As the dough rises and proofs, carbon dioxide is formed; this is why the dough volume increases. The carbon dioxide expands and moves as the bread dough warms and bakes in the oven.

A researcher took samples from the dough of bread on slide A, and from old bread on slide B. The researcher observed the growth of these organisms under the microscope.
