Answer/Explanation:
In eukaryotes, photosynthesis occurs mainly in green plants. These organisms have specialized organelles called chloroplasts that carry out photosynthesis. These contain photoreceptors that absorb photons from the sun through a pigment called chlorophyll, providing the energy to synthesise glucose from carbon dioxide and water.
In contrast, prokaryotes that carry out photosynthesis are able to do so because they have folds in the plasma membrane that permit the attachment of chlorophyll. They do not have specialized membrane-bound organelles like eukaryotes.
The pollutants in 1970 were the highest since recorded history and are declining steadily.
