Answers
Answer:
1.The most common mode of vegetative growth in yeast is asexual reproduction by budding, where a small bud (also known as a bleb or daughter cell) is formed on the parent cell. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell.
2.Viruses, Bacteria, Archaea, Fungi, and Protists.
3.
The bacterium lactobacillus helps in the formation of curd. The microorganisms, yeast is used for the commercial production of alcohol and wine. ... Streptomycin, tetracycline, and erythromycin are some of the commonly used antibiotics; these are made from fungi and bacteria.This is called Friendly Microbes.
4.Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.Louis Pasteur is discovered by the process of fermentation.
5.Aerobic respiration and fermentation are two processes which are used to provide energy to cells. In aerobic respiration, carbon dioxide, water, and energy in the form of adenosine triphosphate (ATP) is produced in the presence of oxygen. Fermentation is the process of energy production in the absence of oxygen.
