Boiling disrupts cell membranes by denaturing the proteins and lipids that make up the cell membrane. The high temperature causes these molecules to lose their structural integrity, leading to the breakdown of the membrane and releasing its contents.
Well, honey, when you boil a leaf in water, you're basically trying to extract all the good stuff out of it. The heat breaks down the cell walls of the leaf, releasing all the nutrients and flavors into the water. So, whether you're making tea or cooking up some greens, boiling that leaf is the first step to getting all the good stuff out of it.
Turning off the Bunsen burner after boiling a leaf is important to prevent the leaf from burning or catching fire. Boiling a leaf is typically done to soften it for further study or observation, and leaving the Bunsen burner on could result in overheating the leaf and damaging it.
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.
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 colour does the clear alcohol become once the leaf is boiled in it

to kill the cell which disrupt the cell membranes and softens the cuticle and cell walls
Yes. All plant cells have a cellular wall, while animal and bacterial cells have cell membranes.
Boiling a leaf for a starch test is done to remove any pigments or chlorophyll present in the leaf that could interfere with the test results. The heat breaks down the cell membranes and denatures enzymes that could potentially affect the starch test. Boiling also helps to soften the leaf tissue, making it easier to extract the starch for testing purposes.

the green pigment, chlorophyll should be removed in order to observe color change during test for starch. in order to do that, the leaf is dipped in boiling water to break cell walls which would facilitate the release of the pigment out of the cell. immersion in ethanol would dissolve the pigment which would be released out of the cells thereby making the leaf appear pale in color.
Cell walls, unlike cell membranes, are not selectively permeable. Less energy would be able to leave the cells.
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.

Chlorophyll in a plant cell is primarily stored in the thylakoid membranes of chloroplasts. These membranes contain pigments such as chlorophyll that are essential for photosynthesis, the process by which plants convert sunlight into energy.
