Why do some microorganisms characteristically form a growth of the pellicle type?

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.

What characteristic of the pellicle makes Euglena different from true plants?
A pellicle is the membrane that envelops a euglena. An euglena is best known and most widely studied member of the phylum Euglenophyta.
What sort of microorganism is yeast?
It is a eukaryotic micro-organism which is classified as a fungi.Yeast is not a taxonomic group. It is a fungal morphology (growth form).
What Plants are dependent on microorganisms for?
changing atmospheric nitrogen to a usable form
What is limiting factors and exponential growth?
Limiting factors is anything you can run out of. Exponential growth is just a form of geometric growth - growth by multiples rather than addition.
How do you think plants decompose and what factors effect decomposition?
What is Decomposition? The term decomposition means “to break down”. It typically corresponds to the disintegration or rupture of complex organic matter into a simpler inorganic matter. It is one of the significant and essential processes of the ecosystem. Hence, decomposition is a metabolic process, taking up raw materials in the form of complex compounds, processing it and then converting it into simpler compounds. Bacteria, fungi and a few other microorganisms initiate the process of decomposition and are known as decomposers. They feed on dead organisms to survive. The decaying and dead animals and plants serve as the raw materials which, on the breakdown, produces nutrients, carbon dioxide, and water, etc. Detritus are the raw materials such as dead animals, plants and their remains. Microbes then process this detritus which are collectively known as saprophytes. Also refer: Putrefaction Let us know more in detail about its process and the major factors affecting the process of decomposition. Factors Affecting Decomposition Following are the important factors affecting the rate of decomposition: Litter Quality The rate of decomposition depends on the structural and chemical properties of litter. For eg., the litter of bryophytes are decomposed at a slower rate due to the presence of lignin like complex chemicals. Temperature Temperature regulates the growth and activity of microorganisms. The temperature is different at different elevations. The species diversity and the microorganism count is affected by environmental changes. Aeration The oxygen present in the pores of the soil helps in the growth of microorganisms. In the water-logged soils, the aerobic microorganisms are absent. Here only anaerobic microorganisms can grow and initiate decomposition. Soil pH The presence of cations and anions governs the pH of the soil, which in turn affects microbial growth. Inorganic Chemicals After decomposition, the elements like potassium, sodium, calcium, magnesium are released into the soil. Some of these are used by the microorganisms for their growth. Thus, it affects the rate of decomposition. Moisture The water present in the soil is responsible for various physiological processes of microorganisms present in the soil. The growth of microorganisms is thus governed by the presence of moisture in the soil.
What is the noun form of characteristically?

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.
What characteristic of the pellicle makes Euglena different from true plants?
A pellicle is the membrane that envelops a euglena. An euglena is best known and most widely studied member of the phylum Euglenophyta.
