If pigments from a particular species of plant are extracted and subjected to paper chromatography,which of the following is the most believable result?
A)Paper chromatography for the plant would isolate a single band of pigment that is characteristic of the particular plant.
B)Paper chromatography would separate the pigments from a particular plant into several bands.
C)The single band of pigment that is isolated is always some shade of green.
D)Paper chromatography isolates only the pigments that reflect green light.

Question

Paper chromatography separates pigments based on their solubility and polarity, so it is likely that pigments from a particular plant will separate into several bands. The number and location of the bands will depend on the specific pigments present in the plant. Therefore, it is unlikely that a single band of pigment characteristic of the plant will be isolated. Additionally, while some plant pigments may reflect green light, not all of them do, so option D is not a reliable statement. Option C is also not reliable, as not all plant pigments are green - there are many different types of pigments that contribute to the overall color of a plant.
