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.
Why is a leaf put in alcohol?
Leaves are often placed in alcohol to preserve and store them for study or observation. The alcohol acts as a fixative, preventing the leaf from decaying and maintaining its structural integrity for long periods of time. Additionally, alcohol can be used to extract and preserve the leaf's pigments or other chemicals for various research purposes.
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.
Why does a leaf become brittle after being boiled in alcohol?
When a leaf is boiled in alcohol, the alcohol acts as a solvent, extracting chlorophyll and other pigments, which can weaken the leaf's cell structure. The heat from boiling also denatures proteins and other cellular components, causing the cell walls to lose their integrity. As a result, the leaf becomes brittle and more fragile, losing its flexibility and resilience. This process is often used in preparation for microscopy to make the leaf more transparent and easier to study.
Why was the leaf placed two times into the boiling water?
The leaf was placed in boiling water twice to ensure that it undergoes complete cell breakdown and to extract chlorophyll effectively. The first boiling helps to kill the leaf and break down the cell walls, making it easier for the chlorophyll to be released. The second boiling often follows immersion in alcohol, which helps to remove pigments and allows for clearer observation of the chlorophyll's presence when tested with iodine. This process is commonly used in experiments to demonstrate photosynthesis and the presence of starch in leaves.
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.
Why was the leaf placed in alcohol?

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 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 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.
What was the colour the clear alcohol become once the leaf is boiled in it?
what colour does the clear alcohol become once the leaf is boiled in it
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 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.
A green leaf placed in a dark room is illuminated by red light The leaf will appear?
