Researchers found that the stomata density on the leaves of a species of plant change as the concentration of Co, in the atmosphere changes. When grown at 350 ppm CO2 the pla has an average density of 300 stomata per mmº, but when grown at 400 ppm CO, the plant has an average density of 250 stomata per mm?.

Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. this explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. these prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast

The answer is reflection.
