What would be found in the clear area that would not be found in the blue area of a starch agar plate after the additon of iodine?

Another organism on the starch agar plate breaks down the starch into smaller sugars, and the starch intolerant organism in turn competes for the smaller sugars. As a result, you will see colonies of the starch user pop up first, and then smaller satellite colonies of the dependant organism will form around them.

Is starch stored in leaves of some plants?
after the plant photosynthesises, it has some left over glucose that the leaves covert into starch. The starch is then stored in the chlorophyl (the green pigment in the leaves). At night or in the dark, the plant can't photosynthesise so it respires the stored starch instead
What organic molecules do potato cells have?
The large molecule found in potatoes is starch.
Contrast the structure and function of starch with those of cellulose in plant cells?
Starch and Cellulose are both built on the same building block, Glucose, but are arranged differently. Because of this, they exhibit some different properties. Most importantly, the human body is capable of digesting starch, but not cellulose.
What are the two polysaccharides found in plants?
starch and cellulose
Is starch found in plant or animal cells?
plants
Is there a method for detecting starch without using iodine?
if you put iodine in food and it contains starch it should change color.
What would be found in the clear area that would not be found in the blue area of starc agar plate after the addition of iodine?
In the clear area that would not be found in the blue area of starch agar plate after the addition of iodine is glucose and exoenzymes. Exoenzymes mainly hydraulic enzymes that leave the cell and breakdown.
How iodine and Benedict's solution tested for starch and glucose?
Ok so all I have found so far is In Benedict's solution Starch-no observable reaction and Starch Amylase-clear blue. In Iodine Starch- Blue Black Starch and Amylase-orange the web page I found this on how ever was very confusing so I'm not sure
Why does starch turn blue with iodine?
the iodine does not turn the starch black."The iodine clock reaction is based around the colour change that occurs when iodine reacts with starch, turning from a clear colour to a black-blue colour." (2) The starch allows the iodine and the iodide ions to bond, forming a triodide ion.I2(aq) + I−(aq) ⇌ I3−(aq)In this reaction, iodide is viewed as a base, and iodine is viewed as an acid.The iodine is a ligand and is surrounded by the starch,as for the colour change, that is due to the iodine absorbing all light wavelengths corresponding to colours, hence not letting any through, so what you are seeing when the solution is black, is the absence of light and colour alltogether,hope that helps

Why does the uncovered part of a life turn blue black after putting iodine solution?
It shows the presence of Starch in the section ot the leave. during photosynthesis when Starch is being produce with the presence of sunlight. it is then tested and found that the exposable part of the leave is containing of Starch.
What is the difference between starch solution and iodine solution?
Starch is composed of amylose and amylopectin, and is not soluble in water due to the presence of amylopectinIodine (I₂) is somewhat soluble in water, but is more soluble in iodide (I⁻) solutions, such as potassium iodide solution (KI).Aqueous iodine molecules (I₂) and iodide ions (I⁻) together will form triiodide ions (I₃⁻), which can react with amylose found in starch to produce a deep-blue colour in the solution. So all of iodide (I⁻), iodine (I₂) and amylose (or starch) are required together to produce the colour.This can be used to test for:Amylose/Starch: Add iodine dissolved in potassium iodide solution to test solution, orIodine: Add starch and potassium iodide solutions to test solution.If the substance being tested for is present, then triiodide ions (I₃⁻) can react with amylose (in starch) to produce a deep-blue colour, that is, a positive result.
What country is iodine found in?
iodine was found in France by Bernard Courtois in 1811 In Boston Massachusetts
Is iodine a synthetic element?
Iodine is found in nature and is not synthesized. As an example, there is iodine in sea water.
Where are macromolecules in corn starch found?
glucose and starch
What is The storage polysaccharide that is found in Plants?
Starch, a polymer of glucose, is used as a storage polysaccharide in plants. It is found in the form of amylose and the branched amylopectin.
Is iodine a pure substance?
Solid iodine can be found as pure crystals.
