What would happen if the amount of starch present if the colour of the leaf if other then green?
If the color of a leaf is other than green, it may indicate a lack of chlorophyll, which is essential for photosynthesis. In such cases, the amount of starch present in the leaf could be reduced, as less photosynthesis would lead to lower glucose production and, subsequently, less starch synthesis. Alternatively, if the leaf contains other pigments, it might still be able to perform photosynthesis efficiently, depending on the type of pigment and the light conditions. Thus, the relationship between leaf color and starch content can vary based on the leaf's ability to photosynthesize.

How amylase breakdown starch?
To test starch: To test starch you take the food sample, and add iodine solution if the colour turns black this means starch is present. To test for protein: To test for protein, you take the food sample and add Biuret A and Biuret B and shake, if the colour turns lilac this means that protein is present.
What colour does the indicator turn when starch is no longer present?
When starch is no longer present, the indicator iodine turns from blue-black to a yellow or brown color. This change occurs because iodine forms a blue-black complex with starch, and in the absence of starch, the iodine remains in its free state, resulting in the lighter color.
Why to destarch a plant?
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis
Is starch more concentration in a tube or in a beaker?
The concentration of starch is the same regardless of whether it is in a tube or a beaker, assuming the same amount of starch is present in both. Concentration is typically expressed as the amount of solute (starch) per unit volume of solvent. It does not depend on the container in which the solute is placed.
What colour does idoine go if there is no starch present in a food?
If iodine is added to a food that does not contain starch, it will typically remain a brownish-yellow color. This is because iodine reacts with starch to produce a blue-black complex, but in the absence of starch, no such reaction occurs, and the iodine retains its original color.
What colors does starch turn if there is a little amount present?
starch will not change its own colour but it can change the colour of iodine solution. iodine solution is originally brown. after adding starch, it will turn into dark blue.
Why does the leaf change colour with iodine?
Iodine reacts with starch present in the leaf, forming a blue-black color complex. The intensity of the color change indicates the amount of starch present in the leaf, which is important for photosynthesis and energy storage. This color change test is commonly used to detect the presence of starch in leaves.
How amylase breakdown starch?
To test starch: To test starch you take the food sample, and add iodine solution if the colour turns black this means starch is present. To test for protein: To test for protein, you take the food sample and add Biuret A and Biuret B and shake, if the colour turns lilac this means that protein is present.
What colour changes where observed with each food tested with iodine?
It change from orange/brown colour to blue/black if starch is present
What color is starch with iodine solution?
it is a yellowish/orange colour but when iodine is present, than it will turn an dark-blue/black colour
What colour does the leaf turn once iodine is added and is no starch?
When iodine is added to a leaf with no starch, the leaf will remain its original color (usually green). Iodine reacts with starch molecules, turning the leaf blue-black if starch is present.
How do you test purity of khoya?
test for starch- dissolving in water+heating+cooling+3-4 drops of tincture iodine, if present, dark blue colour will appear. test for colour- dissolving in water + HCL ,if metanil yellow colour is present, pink colour will appear.
What colour does the indicator turn when starch is no longer present?
When starch is no longer present, the indicator iodine turns from blue-black to a yellow or brown color. This change occurs because iodine forms a blue-black complex with starch, and in the absence of starch, the iodine remains in its free state, resulting in the lighter color.

Why if starch is present there is a blue-black colour?
The blue-black color seen when iodine is added to a solution containing starch is due to the formation of a complex between iodine and starch molecules. This complex is known as "iodine-starch complex," which results in the color change.
Why do you need to add iodine solution to a specimen?
Iodine solution is commonly used to test for starch. If starch is present in a substance (e.g. a leaf which undergone photosynthesis) then the iodien solution would turn blue black. If no starch is present then it remains as light brown.
