2.)germinating seedlings mainly required more carbon dioxide than adult ones

Mark me brainliest

Answer 2

To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. However, seeds respire at a lower rate throughout dormancy. ... As the seeds respire they take in oxygen and release carbon dioxide at roughly the same rate.
