🌱 Plants are green because they use green photosynthetic pigments to harvest sunlight energy.⁠ .⁠ This sunlight energy that they harvest via photosynthetic pigments is used to power the reaction of photosynthesis. In other words, sunlight energy is used to power the transformation of inorganic molecules (CO2 and H2O) into organic molecules (sugar).⁠ .⁠ The photosynthetic pigments are located in the cells that perform photosynthesis, more specifically in organelles called chloroplasts.⁠ .⁠ Interestingly, plants also use photosynthetic pigments that are not green. Most of the time we can’t see these other pigments because their colors get overpowered by the green color pigments.⁠ .⁠ The photosynthetic pigments are fairly hydrophobic, therefore they do not dissolve well in water. This is why @dr.bio4ever used acetone (an organic solvent) to extract them from these spinach leaves.⁠ .⁠ To separate and observe the different photosynthetic pigments that spinach leaves have, he did a paper ch...
