Question

To prepare a temporary slide of yeast culture, yeast granules are added in:
A.Distilled water
B.10% sugar solution
C.90% sugar solution
D.Dilute hydrochloric acid

Answer 1

Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom, the primary yeast originated many several years in the past, and a minimum of one, and 500 species are presently recognized.

Complete answer:
1.Yeasts are unicellular organisms that evolved from multicellular ancestors with some species having the flexibility to develop cellular characteristics by forming strings of connected budding cells acknowledged as pseudohyphae or false hyphae.
2.Yeast size varies greatly, contributing factors are species and atmosphere, usually activity 3-4μm in diameter, though some yeasts will grow to 40 μm in size.
3.Most yeasts reproduce asexually by mitosis and lots of do therefore by the uneven division method acknowledged as budding. With their non cellular growth habit, yeasts will be contrasted with molds that grow hyphae. Plant species that may take each form (depending on temperature or different conditions) are called dimorphic fungi.
4.The yeast granules ought to be adscititious to a wet bread so that facilitate growth and they will reproduce simply.

Hence, the correct answer is option(B)

Note: The yeasts species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols in a method acknowledged as fermentation.
The product of this reaction is used in baking and the assembly of alcoholic beverages for thousands of years.
