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 did leaf had to be boiled in ethanol when testing leaf for starch?
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.
Which leaf would contain more chlorophyll a dark green leaf or a light green leaf Is this a trick question?
this is not a trick question it just needs thought a dark green leaf would have more chlorophyll because chlorophyll is the substance that causes the leaf to turn green
When light strikes a green leaf how does this explain why leaves appear green?
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
Why does the leaf of a plant appear green?
The leaf of a plant appears green because of a pigment called chlorophyll. Chlorophyll absorbs sunlight and uses it to make food for the plant through a process called photosynthesis. The green color of chlorophyll reflects green light, making the leaf look green to our eyes.
What happens when green leaf is boiled in water?
it will make holes
Why does leaf turn light green when boiled in ethanol?
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour) wash with water to rehydrate and soften the leaf
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 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 change is observe when a leave was boiled in warm water in a experiment?
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.
What happen when green leaves boiled in water?
turns pale
What colour does the clear alcohol become once the leaf is boiled in it?
When a leaf is boiled in clear alcohol, the color of the alcohol can change depending on the pigments present in the leaf. For example, if a green leaf is used, the alcohol may take on a green hue due to the release of chlorophyll and other pigments. Similarly, boiling leaves with red or purple pigments can result in a reddish or purplish tint to the alcohol. The specific color change will vary based on the type of leaf and its pigment composition.
Why green leaves turn pale when boiled in water?
on boiling leaves loose chlorophyll
When testing for starch why the leaf is boiled?
to denature the enzymes going to kill the leaf
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.
What is extracted from boiled leaf?
Air. Basically that's the answer.
What is the green part of the leaf?
The green part of the leaf is green because of the chlorophyll inside
