Black
Iodine turns blue-black in the presence of starch.
Iodine turns a yellow-brown color when there is no starch present in a leaf. This color change indicates the absence of starch, which is detected by the iodine as it interacts with the leaf's compounds.
Iodine turns blue-black in color in the presence of starch.
If the endosperm contains starch, it will turn blue-black in the presence of iodine solution. This color change indicates the presence of starch in the endosperm, as iodine reacts with starch to form a starch-iodine complex, resulting in the blue-black color.
Iodine turns a blue-black color when it comes in contact with starch. This color change indicates the presence of starch, making iodine a common reagent for detecting the presence of starch in various substances.

BlackAns2:It is very unlikely that a ripe banana will have enough starch to turn iodine black. When iodine turns black, it is a positive test for the presence of starch.
dark blue - purple

Yes, iodine is added when testing for starch. Iodine will change color to blue-black in the presence of starch. This color change helps to indicate the presence of starch in the substance being tested.
Use an iodine solution. it should be orange to brown to begin with, if there is a starch present, it will turn blue-black.
Iodine turns blue-black in the presence of starch due to the formation of a complex between iodine and starch molecules.
En leaves do not turn blue-black with iodine because they do not contain starch, which is what iodine reacts with to produce the characteristic color change. Starch is a carbohydrate produced by plants through photosynthesis, so leaves that do not contain starch will not show the blue-black color reaction with iodine.
