so the waxy cuticles can rub off the surface of the leaf.
a leaf has a cell wall and if you did not put the leaf in the boiling water it would not break down so therefore you would not be able to do a proper starch test on the leaf so the answer to this question is to break the cell wall down so you can test for starch properly i hope i helped you :) yeap
What else can I help you with?
Why do we have to boil leaf in water what happens if this step is not done?
Boiling a leaf in water is a crucial step in experiments such as testing for starch because it helps to break down the cell walls, making the starch more accessible for detection. If this step is skipped, the starch present in the leaf may not dissolve properly, leading to inaccurate or inconclusive results when testing for its presence. Additionally, boiling denatures enzymes that could interfere with the test.
How do you get a starch in a leaf conclusion?
To test for starch in a leaf, first, ensure the leaf has been destarched by placing it in darkness for 24 hours. Then, boil the leaf in water to kill it, followed by soaking it in alcohol (usually ethanol) to remove chlorophyll. After rinsing the leaf in warm water, immerse it in iodine solution. A blue-black color indicates the presence of starch, confirming that photosynthesis has occurred.
Should I boil the water first and then add bleach or add bleach then boil?
If you want the water to be more than hot enough to activate the bleach, then boil the water first. Boiling bleach is not advised, because that would produce deadly chlorine gas.
What test can we do to determine if starch is produced by the green plants?
To determine if starch is produced by green plants, you can perform an iodine test. First, take a leaf from the plant and boil it in water to kill the cells, then immerse it in alcohol (such as ethanol) to remove chlorophyll. After rinsing the leaf in warm water, add a few drops of iodine solution; a blue-black color change indicates the presence of starch, confirming that the plant has produced it through photosynthesis.
Which will boil first salt water or plain water?
salt water boiled first i had to do an experiment and salt water won
How do you dissolve starch in water?
Starch dissolves in boiling water. As a result, the most useful method is to boil water in a pan, and add starch, stirring until it is dissolved.

How do you find out how healthy your aquifer is?
You can find out how healthy your aquifer is by testing the water for microbes. If the water contains microbes, boil it before drinking it.
Why dou use so much water to boil noodles?
Pasta added to water before it starts to boil gets a heat start on mushiness. Pasta quickly begins to break down in tepid water as the starch dissolves. You need the intense heat of boiling water to "set" the outside of the pasta, which prevents the pasta from sticking together. That's why the fast boil is so important; the water temperature drops when you add the pasta, but if you have a fast boil, the water will still be hot enough for the pasta to cook properly. http://whatscookingamerica.net/Pasta_Rice_Main/pasta.htm
What kind of solution you get when you mix starch in water?
It depends on how much percentage of of starch solution is to be made. For an example: To make 20% of Starch Solution, you need to pour 20grams of starch powder in 100ml of water. After the powder is dissolved, boil the water. - Ridwan T. Haque International School Dhaka Class of 2009

How can you remove the starch from a leaf?
To remove starch from a leaf, you can perform a simple experiment using iodine solution. Boil the leaf in alcohol to remove the chlorophyll, then soak it in hot water to soften it. After that, rinse the leaf with cold water and apply iodine solution — the starch will turn blue-black, indicating its presence.
How do you starch clothes?
1. Mix a package of starch in a little amount of water to dissolve it 2. Boil water in a pot and pour it into it mixtures the dissolved starch and water 3. Stir well the boiled mixtures to prevent lumps from forming 4. Add cold water to produce the desired consistency 5. Starch the wet white garments first 6. Soak each piece in the liquid starch and squeeze 7. Wring and hang the garments to dry 8. Keep the dry clothes in a box pror to ironing
