Different types of cells reach different sizes. In general the reasons for cell size limits are due to the mechanisms needed for cell survival and how cells requirements are met by the structures that form and are contained within cells.
It wasn't that the favourable traits were passed down through generations of species, it's that natural selection removed the species who simply couldn't survive. Here's an example: There are two species of moth in a forest, one is brown and the other is black. The trees in the area have trunks that are brown like the moth's wings, so it can camouflage very well compared to the black moths. Eventually, more black moths were being eaten by various amphibians and bugs than brown moths. So, the favourable trait of brown wings continued to be passed on, whereas the black wings went extinct as they were all eaten. Hope that helped :D

Answer:
According to earthobservatory.nasa.gov/,
"The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn’t escape the ocean easily."
