The presence of dye in the veins of a leaf indicates the movement and distribution of water and nutrients through the plant's vascular system, specifically the xylem and phloem. It shows how effectively the plant can transport these essential substances for photosynthesis and growth. Additionally, the dye can help visualize the leaf's vascular structure and aid in studies related to plant physiology and health.

What is chemical indicator dye?
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
Where in the broth column in resazurin dye located?
In resazurin dye, the broth column typically refers to the medium in which the dye is dissolved for microbial testing. The dye is usually found in a liquid phase, where it can indicate metabolic activity through color changes. When bacteria metabolize resazurin, it is reduced to resorufin, resulting in a color shift from blue to pink, indicating the presence of viable microorganisms. Therefore, the broth column is crucial for assessing microbial growth and viability.
What does the presence of blue color means in variegated leaf experiment of photosynthesis?
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not. The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.
Why does lipids turn redish brown when added to Sudan iv dye?
Sudan IV dye is a fat-soluble dye that binds to lipids in a solution. When lipids are added to Sudan IV dye, the dye molecules bind to the lipids and cause them to appear redish brown in color. This is a characteristic reaction that helps to identify the presence of lipids in a substance.
What substance is stained by Sudan dye?
Sudan dye stains lipids or fats. It is commonly used in laboratory settings to help visualize and detect the presence of lipids in cells or tissues.
What is chemical indicator dye?
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
What happened to the celery in dye solution?
The veins of the celery turn the color of the dye. It's very cool when you slice it open.
What is the purpose of Resazurin dye?
Resazurin dye is used in microbiological culture media for anaerobes as an indicator of the presence of oxygen. The dye turns pink when oxygen is present.

What is phlebography?
an x ray test that provides an image of the leg veins after a contrast dye is injected into a vein in the patient's foot.
Why do they put dye through your veins?
Medical procedures involving the use of "dye" through your veins enables the veins to show up more clearly when scanned by a CT/MRI machine, or similar. This is useful when assessing levels of blood-flow around the body, and will show up where any "blockages" may be occurring. Similar procedures involve ingesting (swallowing) a small amount of "dye"; this type of process would be used to assess the stomach, small intestine and colon. Usually the "dye" is actually a non-harmful radioactive substance, as opposed to a liquid of a concentrated colour (which is how most people consider "dye"). It is completely harmless, and breaks down within a few hours of being injected.
What is the procedure called when you x-ray using dye in the veins?
The procedure is called venography or contrast venography. It involves injecting a contrast dye into the veins to make them visible on X-ray images, allowing healthcare providers to assess the condition of the veins and detect any abnormalities, such as blood clots or blockages. This imaging technique is often used in cases of suspected deep vein thrombosis or other vascular issues.

What affects the fastness of a fabric dye?
The fastness of a fabric dye is affected by factors such as the type of dye used, the fabric material being dyed, the dyeing method employed, and post-dyeing treatments like washing and exposure to light. Additionally, the pH of the dye bath and the presence of chemicals that can interact with the dye also influence the fastness of the dye.
What is a Tri-phasic ct scan?
A tri-phasic CT scan is a scan which will show three different stages of dye uptake in the body. The first phase will be before the injection of the dye, the second stage will be for when the dye is in the arteries (roughly 20 seconds after injection) and the third phase will be when the dye has reached the veins (a few minutes later). Sometimes a fourth scan is also done to show the dye uptake in the kidneys and bladder. A tri-phasic scan clearly delineates lesions in the liver and will show problems and irregularities in the arterial and lymphatic system.
What is an X ray of the renal pelvis using a dye called?
Intravenous Pyelogram or IVP is the investigation of the renal pelvis using x-ray dye. The dye is injected into the veins and then a series of images are taken showing the kidney in various stages of dye uptake. X-rays are taken until most of the dye has entered the bladder. Often an x-ray after the bladder has been emptied is taken as well.
