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.
What did you see on the leaf in the test tube when testing for starch?

What will happen to a leaf when you put iodine solution into it?
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
Why didn't the margins of the leaf turn blue black after the use of the iodine solution?
The margins of the leaf did not turn blue-black because there was no starch present in that area. The iodine solution reacts with starch to produce a blue-black color. If the margins did not turn blue-black, it suggests that there was no starch in that part of the leaf.
WHY WAS THE LEAF TURN WHEN IODINE SOLUTION WAS PLACE ON IT?
The leaf turned black when iodine solution was placed on it because iodine reacts with starch present in the leaf, forming a dark blue-black complex. This color change is a common test used to detect the presence of starch in a leaf.

What is the answer A leaf was tested for starch the iodine solution stayed orange what does that tell you about the leaf?
If the iodine solution stays orange after testing a leaf for starch, it indicates that the leaf does not contain starch. Starch would typically turn the iodine solution blue-black in color. Therefore, the orange color suggests that the leaf did not produce a significant amount of starch through photosynthesis.
What will happen to a leaf when you put iodine solution into it?
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
What is the role of iodine in testing a leaf for starch?
A hot bath of ethanol decolorizes the leaf by washing out the chlorophyll. If the leaf is not decolorized, you cannot see the blue-black stain that results from the iodine reacting with the starch.
Why did the leaf turn blue black when iodine was added in the starch test?
The leaf turned blue-black in the starch test because iodine forms a complex with starch molecules, resulting in the blue-black color change. This color change indicates the presence of starch in the leaf tissue.
Why didn't the margins of the leaf turn blue black after the use of the iodine solution?
The margins of the leaf did not turn blue-black because there was no starch present in that area. The iodine solution reacts with starch to produce a blue-black color. If the margins did not turn blue-black, it suggests that there was no starch in that part of the leaf.
WHY WAS THE LEAF TURN WHEN IODINE SOLUTION WAS PLACE ON IT?
The leaf turned black when iodine solution was placed on it because iodine reacts with starch present in the leaf, forming a dark blue-black complex. This color change is a common test used to detect the presence of starch in a leaf.
What is the color of the leaf at the end of the experiment that test for starch?
the color of the leaf become brown-black after the iodine solution was added.
Why do green leaves turn blue black when iodine is added?
because the leaves have photosynthesized- glucose is produced. therefore, the excess glucose is converted to starch. The starch is then stored in the leaf-starch is what causes the "green" leaf to turn blue black, as iodine turns blue-black when it reacts with starch.:P
What effect the iodine solution have on a leaf?
Iodine solution can test for the presence of starch in a leaf. When iodine solution is applied to a leaf, it will turn blue-black in areas where starch is present. This is because iodine reacts with starch to form a bluish-black complex.
What colour should the leaf turn when iodine is added?
The leaf should turn blue-black when iodine is added, indicating the presence of starch.
