in pellicle formation small masses of cells gather at the top of the nutrient broth. these organisms (masses of cells) are aerobes. the oxgen concentration is greatest at the top which would explain growth of the pellicle type.

How do microorganisms help in making soil fertile?
Microorganisms help in making soil fertile by decomposing organic matter, releasing nutrients that plants can use for growth. They also improve soil structure by producing substances that help bind soil particles together, reducing erosion. Some microorganisms, like nitrogen-fixing bacteria, can convert atmospheric nitrogen into a form plants can use, further enhancing soil fertility.
What Plants are dependent on microorganisms for?
Plants are dependent on microorganisms for nutrient uptake (like nitrogen fixing bacteria), disease resistance (beneficial microbes can protect plants from pathogens), and overall growth and health (symbiotic relationships with mycorrhizal fungi help plants absorb water and minerals).
What characteristic of the pellicle makes Euglena different from true plants?
The pellicle of Euglena is made of protein strips, providing flexibility and enabling movement, while true plants have a cell wall made of cellulose. This allows Euglena to exhibit more animal-like movement, such as swimming and changing shape.
What is the use of Peptone media?
Peptones :Small polypeptides that are intermediate products in the hydrolysis of proteins. The term is often used for any partial hydrolysate of proteins as, e.g., bacteriological peptone, which is used as a medium for the growth of micro-organisms. Enzymatic digests of protein that provide nitrogen in a form that is readily available for bacterial growth. All Proteose Peptone products are used in preparing microbiological culture media and in producing bacterial toxins. It has been reported that Proteose Peptone as supplementation to defined medium resulted in significant increases in cell number and specific monoclonal antibody production in batch culture.
The term nitrogen fixation refers to the?
biological process where certain microorganisms convert atmospheric nitrogen into forms that plants can use for growth, such as ammonia or nitrate. This process is essential for maintaining soil fertility and the overall nitrogen cycle in ecosystems.
What is the film of cells at the surface of a broth called?
The film of cells at the surface of a broth is typically referred to as a "pellicle." This pellicle forms as a result of bacterial growth and can be observed in certain bacterial cultures, especially those with aerobic bacteria that form biofilms at the air-liquid interface.
What is the noun form of characteristically?
The word 'characteristically' is the adverb form for the noun characteristic.
What is the characteristics of form?
The word 'characteristically' is the adverb form for the noun characteristic.
What is importance of pellicle and how to achieve?
A pellicle is a tacky film that forms on the surface of meat when smoking, which helps the smoke flavor adhere better to the meat and helps retain moisture during cooking. To achieve a pellicle, first pat the meat dry with paper towels, then let it sit in the refrigerator uncovered for a few hours to air-dry and allow the pellicle to form before smoking.
What is the adverb for traditional?
The word traditional is an adjective form of the noun tradition. The adverb form is traditionally (historically, characteristically).
Why do some organisms form a pellicle on liquid media?
The evolutionary advantage that would be there to the formation of a pellicle in a liquid medium by a bacterium is they could form colonies and have a greater chance of survival. Two ways to determine motility of a bacteria is using a agar deep or the hanging drop technique.
Why is the mouth such a good habitat for microoganisms?
The mouth offers a moist environment with constant temperature and a food source in the form of debris and nutrients, providing an ideal habitat for microorganisms to thrive. The presence of saliva also helps create a protective film that allows microorganisms to adhere and form biofilms, further supporting their growth.
Name the microorganisms which can fix atmospheric nitrogen in the soil?
Examples of microorganisms that can fix atmospheric nitrogen in the soil include certain species of bacteria such as Rhizobium and Azotobacter. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can utilize, ultimately promoting plant growth and soil fertility.
What is the definition of scaling?
one of the many small platelike dermal or epidermal structures that characteristically form the external covering of fishes, reptiles, and certain mammals.
