Why did the leaf turn brittle in testing a leaf for starch?
The leaf turns brittle during the testing the leaf for starch because the ethanol extracts the all water content from 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.
What happens when you soak a leaf in boil ling water for two minutes?
Soaking a leaf in boiling water for two minutes can cause the leaf to lose its color and become wilted. The heat can also break down the cell structure of the leaf, causing it to become mushy and lose its structural integrity.
What happens to playdough after cooling?
The material become brittle.
What would happen if a leaf was placed in distilled water?
Placing a leaf in distilled water would allow water to enter the leaf through osmosis, leading to an increase in turgor pressure within the cells. This influx of water could cause the leaf to become turgid and firm.
Why did the leaf turn brittle in testing a leaf for starch?
The leaf turns brittle during the testing the leaf for starch because the ethanol extracts the all water content from the leaf.

How does a leaf feel after being boiled in alcohol?
After being boiled in alcohol, a leaf would likely feel very brittle and fragile. The heat from the boiling process would cause the leaf's cells to break down, leading to a loss of structural integrity. Additionally, the alcohol could further dehydrate the leaf, making it even more delicate and prone to crumbling.
How do temperatures affect paint?
In paintball, higher temperatures cause the gelatin casing to melt, causing the overall paintball to become sticky and mushy. Lower temperatures will cause them to become brittle and crack instead. However, there are some winter-adjusted paints that will not become brittle in cold temperatures.
What does the leaf look like after it had been heated with ethanol?
After being heated with ethanol, the leaf may appear wilted or discolored due to the ethanol extracting the pigments from the leaf. The leaf may also become brittle or fragile as a result of the heat and the alcohol treatment.
What happens if you spread a brittle leaf out on a white tile?
it will get dry and it will die
What is the common cause of mechanical seal leak?
The rubber or plastic seals become brittle with age and crack, or simply wear out.
Why brittle fracture occurs in grey cast iron?
Gray cast iron contain high amount of carbon in the form of flakes, the major strengthening element. These flakes cause the cast iorn to become strong yet brittle, in other words they become stress risers due to their brittleness, hence the part itself becomes brittle.
How does the brittle bush adapt to survive in the desert?
in general, brittle bushes in the desert have deep roots to absorb as much water as possible (or is that cacti?) anyway, they have tightly curled leaves that reduce moisture loss. Leaf pubescence (leaf hairs) grow on brittle brush. These leaf hairs reduce the amount of light the plant is able to absorb, therefore limiting the rate of photosynthetic activity.
What happens when you soak a leaf in boil ling water for two minutes?
Soaking a leaf in boiling water for two minutes can cause the leaf to lose its color and become wilted. The heat can also break down the cell structure of the leaf, causing it to become mushy and lose its structural integrity.
