It does nothing apart from semi fermint the leaf
When a leaf is placed in alcohol, the alcohol acts as a solvent and removes the chlorophyll from the leaf, causing it to lose its green color. Other pigments present in the leaf may remain, giving the leaf a different color appearance.
what colour does the clear alcohol become once the leaf is boiled in it
The leaf is boiled in alcohol to remove the chlorophyll and other pigments that can interfere with the starch test. This process helps to showcase the presence of starch in the leaf by removing any substances that may obscure the results.
When a leaf is placed in boiling alcohol, the alcohol will extract the pigments from the leaf, resulting in coloration of the alcohol solution. This process is used in laboratories for pigment extraction and analysis.
Alcohol is a solvent: It dissolves stuff. The leaf is porous, full of holes. When the leaf is placed in the alcohol, the alcohol gets into the leafs, and dissolves the pigments in the leaf, probably chlorophyll, which is green. This will turn the alcohol green.
It really depends on the type of leaf and the color of the leaf.

After being boiled in alcohol, a leaf would likely feel very brittle and fragile. The heat from the boiling process would cause the leaf's cells to break down, leading to a loss of structural integrity. Additionally, the alcohol could further dehydrate the leaf, making it even more delicate and prone to crumbling.
When a leaf is boiled in alcohol, the alcohol extracts compounds such as essential oils, pigments, and other chemical substances from the leaf. This process is known as maceration and it allows for the extraction of specific components from the plant material.

When testing for starch, the leaf is boiled in alcohol to remove the chlorophyll that may mask the iodine-starch color change. If the leaf turns blue-black after applying iodine, it indicates the presence of starch. If the leaf remains discolored, it suggests that starch is absent, as the iodine did not react with any starch molecules present in the leaf.
Boiling the leaf in ethanol removes chlorophyll, which can interfere with the test for starch using iodine. This process helps to ensure accurate detection of starch in the leaf tissue without any color interference from chlorophyll.
When a leaf is boiled in warm water, the heat can cause the cell membranes in the leaf to rupture. This can result in the loss of color pigments in the leaf, causing it to turn pale or translucent. Additionally, the proteins in the leaf may denature due to the heat, leading to changes in the leaf's structure and texture.
