Why is no locating agent needed when inks or grass pigments are analysed by chromatography?
Inks and grass pigments usually contain naturally occurring compounds that can act as locating agents, such as chlorophyll in grass pigments and dyes in inks. These compounds already have distinctive colors and properties that can easily indicate the separated components on the chromatogram without the need for an additional locating agent.

What contains pigments needed for photosynthesis?
Chloroplasts contain pigments needed for photosynthesis, including chlorophyll a, chlorophyll b, carotenoids, and xanthophylls. These pigments capture light energy and convert it into chemical energy during the process of photosynthesis.
What may store water needed chemicals wastes pigments in plant cell?
central vacuole
Why are pigments such as chlorophyll needed?
Pigments such as chlorophyll are needed in plants for photosynthesis. Chlorophyll absorbs light energy, which is essential for converting carbon dioxide and water into glucose and oxygen. This process provides the plant with energy and is crucial for its growth and survival.
What may store water needed chemicals wastes pigments in a plant cell?
The vacuole is the organelle in a plant cell responsible for storing water, nutrients, pigments, and waste products. It helps maintain turgor pressure and can store various substances needed for the cell's activities.
Why are pigments such as chorophyll needed for photosynthesis?
Pigments like chlorophyll are needed for photosynthesis because they are capable of absorbing light energy. This energy is then used by plants to convert carbon dioxide and water into glucose, a process crucial for the plant's growth and survival. Without chlorophyll, plants wouldn't be able to capture and utilize sunlight effectively for photosynthesis.
Why is alcohol used when testing to see if chlorophyll is needed for photosynthesis?
Chlorophyll dissolves (becomes mobilized) in alcohol. Once mobilized, it can be separated from the other pigments by chromatography.
Why are pigments needed for photosynthesis?
Pigments are needed for photosynthesis to capture light energy. Specifically, pigments such as chlorophyll absorb certain wavelengths of light necessary for the conversion of light energy into chemical energy during the process of photosynthesis. Without pigments, plants would not be able to harvest light to fuel their growth and metabolism.
What contains pigments needed for photosynthesis?
Chloroplasts contain pigments needed for photosynthesis, including chlorophyll a, chlorophyll b, carotenoids, and xanthophylls. These pigments capture light energy and convert it into chemical energy during the process of photosynthesis.
What items are necessary for photosynthesis?
Chlorophyll pigments are needed with enzymes. Water and CO2 needed as raw materials.
What sign is needed for locating fire equipment?
OSHA does not specify that signs are required.
What tools were impportant to a limner?
They needed pigments, linseed oil, grindstone, muller (to make paint), a color box (to carry pigments in), and a paint brush.
What are needed so that a plant can undergo photosynthesis?
Mainly Photosynthetic pigments and organells,Enzymes and DNA
What may store water needed chemicals wastes pigments in plant cell?
central vacuole
Why are pigments such as chlorophyll needed?
Pigments such as chlorophyll are needed in plants for photosynthesis. Chlorophyll absorbs light energy, which is essential for converting carbon dioxide and water into glucose and oxygen. This process provides the plant with energy and is crucial for its growth and survival.
What is the complex mixture of salts and pigments produced by the liver and stored in the gallbladder until needed called?
Bile.
What may store water needed chemicals wastes pigments in a plant cell?
The vacuole is the organelle in a plant cell responsible for storing water, nutrients, pigments, and waste products. It helps maintain turgor pressure and can store various substances needed for the cell's activities.
What does Plants use pigments to collect or trap?
Plants use pigments to collect or trap light energy for photosynthesis. Pigments such as chlorophyll absorb specific wavelengths of light, which are then converted into chemical energy that the plant can use to produce sugars and other molecules needed for growth and development.
