What happens to a leaf when placed in the alcohol and what the alcohol removed from it?
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 happens to the color of the alcohol when a leaf is boiled in it?
When a leaf is boiled in alcohol, the chlorophyll in the leaf is extracted and dissolves in the alcohol. The alcohol may change color depending on the pigments present in the leaf, such as turning green if chlorophyll is present.
Why was the leaf placed in alcohol?
The leaf was placed in alcohol to preserve it and prevent decay. Alcohol acts as a preservative by killing bacteria and other organisms that can cause the leaf to deteriorate.
What was the colour the clear alcohol become once the leaf is boiled in it?

What happens when you put a leaf in boiling alcohol?
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.
What happen when leaf boil in alcohol what the alcoholl remove from the leaf?
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.
Why was the leaf placed in alcohol after being in boiling water?
Placing the leaf in alcohol after boiling water helps to remove the chlorophyll from the leaf, making it easier to see the plant's internal structures under a microscope. The alcohol also dehydrates the leaf, preserving it for further examination.
Why did the alcohol turned green when the leaf was put into it?
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.
What happens when iodine is dropped into a leaf?
When iodine is dropped onto a leaf, it reacts with starch present in the leaf to form a blue-black color. This color change is used to test for the presence of starch in the leaf tissue. Absence of blue-black color indicates that starch is not present in the leaf.
Explain what happened when a leaf is placed in alcohol and what it took from it?
When a leaf is placed in alcohol, typically ethanol, the alcohol acts as a solvent, extracting chlorophyll and other pigments from the leaf. This process helps to decolorize the leaf, making it pale or transparent. The alcohol disrupts the cell membranes, allowing the pigments to dissolve into the alcohol solution. As a result, the leaf's chlorophyll is removed, which is essential for photosynthesis, leaving behind a clear or colorless structure.
Why leaf bits will settled in alcohol?
Leaf bits settle in alcohol due to differences in their densities. The alcohol solution has a lower density compared to the leaf bits, causing the bits to sink and settle at the bottom of the container over time. This phenomenon is known as sedimentation.
What color does the clear alcohol become once the leaf is boiled in it?
It really depends on the type of leaf and the color of the leaf.
