How many pigments were separated in each type of leaf?
In spinach leaves, two pigments were separated: chlorophyll a and chlorophyll b. In maple leaves, one pigment was separated: carotene.
How is chromatography related to photosynthesis?
The process of chromatography relates to the overall process of photosynthesis because photosynthesis is the source of food for plants. Plants use sunlight, CO2 and water to make energy in the form of glucose. The role of pigments in this is that pigments help to create energy in plants by absorbing sunlight. Pigments can absorb or reflect certain light waves according to their specific wavelengths which can be determined by the colour of the pigment. Different colours of pigments have different corresponding wavelengths. The pigment, chlorophyll, found in most plants is the one most associated with photosynthesis. This pigment reflects green wavelength because they provide less energy and reflects it for us to view the plant as green. An example of this would be spinach. This green plant contains multiple pigments. It contains chlorophyll which reflects green light and also contains multiple other pigments which pass through the leaf to be used in photosynthesis. Particularly intense reflection increases the colour of the plant and since green plants contain an abundance of chlorophyll to reflect as much green light as possible, we see spinach as a dark green plant.
The provitamin form of vitamin A found in plant pigments is known as?
The provitamin form of vitamin A found in plant pigments is known as beta-carotene. Beta-carotene is a type of carotenoid that can be converted into active vitamin A in the body as needed. It is commonly found in fruits and vegetables such as carrots, sweet potatoes, and spinach.
What pigments are found in green lettuce leaves?
The green color in lettuce leaves comes from chlorophyll, which is the primary pigment responsible for photosynthesis. Additionally, there may be small amounts of other pigments like carotenoids, which can contribute to the overall color of the leaves.
Does spinach have chloroplasts?
Spinach is a plant. So they do have chloroplasts
How does the pigments compare of malabar spinach to regular spinach?
The pigments of Malabar spinach are purplish while those of regular spinach are entirely green.
Which pigments did you identify from the spinach leaf?
Chlorophyll, carotenoids, pheophytins and xanthophylls
What is the pH value of palak extract?
The pH value of palak (spinach) extract can vary depending on factors such as the freshness of the spinach and any processing it has undergone. On average, palak extract is slightly acidic with a pH range typically around 5.5 to 6.5.
How many pigments were separated in each type of leaf?
In spinach leaves, two pigments were separated: chlorophyll a and chlorophyll b. In maple leaves, one pigment was separated: carotene.
The pigments melanin and what contribute to skin color?
The pigments melanin and carotene contribute to skin color. Carotene is found in foods such as carrots, sweet potatoes, apricots, spinach and broccoli.
Why does spinach extract turn red in bright light?
I don't know the source of your "bright light". If it's sunlight, which of course has some UV in it, or if you take the extract into a dark room and shine a "black light" on it, you will see fluorescence. The source of the red color is chlorophyll. When in place in the leaf, the electrons of chlorophyll absorb solar energy. These excited electrons then fall into an electron transport chain that will strip them of the added energy, using that energy to form ATP and NADPH. The red color you see when you illuminate chlorophyll in a spinach extract with UV is the fall of those "excited state electrons" back into their "ground state". In falling, they shed their energy in the form of red light.
Does vitamin A have any alternate names?
Yes. it is also called Retinol (because it produces the pigments for the retina of the eye) and Carotenoids (dark colored pigments in plant foods, like carrots and spinach).
Why does spinach not give you a great amount of iron when you eat it?
Spinach, as well as other vegetables that have iron in them, have a form that is not very easily absorbed (non-heme iron), while iron from animal sources is much more easily absorbed (heme iron).
What has the author William Flora written?
William Flora has written: 'Investigation of the interaction between sulfur dioxide and the photosynthetic pigments from spinach'
Experiment on the effect of the PH of enzymatic reaction using hydrogen peroxide and extract of spinach leaf?
To investigate the effect of pH on the enzymatic reaction with hydrogen peroxide and spinach leaf extract, set up multiple test tubes with varying pH solutions. Then, add equal amounts of hydrogen peroxide and spinach leaf extract to each test tube and observe the rate of reaction. Measure the rate of reaction by recording the production of gas or color change over a set period of time. This will provide insights into how pH influences the enzyme activity in the reaction.
