Why do you place a leave in hot water then rinse it with cold water?
Placing a leaf in hot water helps to extract flavor and essential oils from the leaf. Rinsing it with cold water helps to stop the cooking process and preserve the color and texture of the leaf.
What the colour of the leaf after rinsing?
The color of a leaf after rinsing can vary depending on the type of leaf and any substances present on it before rinsing. Generally, rinsing may remove dirt, dust, or residues, revealing the leaf's natural color, which is often green due to chlorophyll. If the leaf was discolored or stained before rinsing, it may appear brighter or cleaner after being washed. However, some leaves may retain discoloration if they are damaged or affected by disease.
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.
After rinsing with salt water should you rinse with water?
No, it is not necessary to rinse with water after rinsing with salt water. The salt water rinse is typically done to help clean the mouth and promote healing, so rinsing with water afterwards may dilute its effects. Just spit out the salt water after rinsing.
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.

Why is the leaf rinsed in the water?
Salad leaves picked from the garden may be covered in soil and or insects. Rinsing them in clean water removes this making them nicer to eat.

When testing a leaf for starch why is it rinsed in cold water after it is boiled?
Rinsing a leaf in cold water after boiling it is done to stop the enzymatic activity that breaks down starch. Boiling the leaf softens the cell walls, allowing the iodine solution to penetrate and react with any starch present. Rinsing in cold water halts the enzymatic breakdown of starch, preserving the blue-black color reaction with iodine, indicating the presence of starch in the leaf.
Should bath water be used for rinsing?
yes
How do you remove green color form the leaf?
To remove the green color from a leaf, you can use a method called decolorization. This typically involves boiling the leaf in alcohol, such as ethanol, which extracts chlorophyll and removes the green pigment. Afterward, rinsing the leaf in a solution of water and iodine can help visualize any remaining starches, as the iodine will turn blue-black in the presence of starch, indicating the areas where chlorophyll was present.
The loss of water from plants back into the atmosphere?
The "loss" of water vapor from stoma on the underside of the leaf is called transpiration. Transpiration also provides assistance in the uptake of water by plants, as water is lost through the leaves a low pressure is created within the leaf, assisting with the "suction action" of water being drawn up the vessels in the plant stem (simplified explanation
