Question

38 Please ignore my selection, please give me the true answer. 

**Question:** Which of the following lineages forms its protective structures from silica dioxide and is responsible for ~40-45% of the oxygen gas (O₂) in the atmosphere? - ○ red algae - ○ diatoms - ● dinoflagellates - ○ euglenozoans **Explanation:** The correct answer is "diatoms." Diatoms are a group of microalgae that have a significant role in global oxygen production. They construct their cell walls out of silica dioxide, forming intricate and beautiful glass-like structures. Despite the selection of "dinoflagellates" in the options, diatoms are the primary contributors to atmospheric oxygen in this capacity.
