Question

which technique is used to determine plant pigment and rate of photosynthesis? microscopy chromatography electrophoresis dna sequencing

Explanation:

Chromatography can separate plant pigments based on their different affinities for the stationary and mobile phases, and can also be related to studying aspects of photosynthesis as pigments are key in the process. Microscopy is mainly for visualizing structures, electrophoresis for separating charged molecules like proteins and nucleic - acids, and DNA sequencing for determining the order of nucleotides in DNA.

Answer:

B. chromatography
