In eukaryotic organisms, photosynthesis takes place in the chloroplast. Do they instead use a wand to direct all of the sun's photos toward the creation of food molecules? Yes, the chloroplasts contain a hydrophilic pigment that absorbs green light - Yes, water and hexane extracts have different colors - Yes, molecules that cannot be dissolved in water dissolve well in hexane - Yes, I Bacterial Quantification by Culture Labster Answer Key 1. The top band of pigments in the separation are carotenoids called carotenes, most likely beta-carotene, and appear yellowish-orange. In case you dont know and pick the wrong one, you can have another go.
