(N/A) $1$. Germination is an active metabolic process that requires a significant amount of energy.
$2$. During germination,the embryo resumes growth,which leads to a sharp increase in the rate of cellular respiration.
$3$. This process requires a continuous and adequate supply of oxygen $(O_2)$.
$4$. Seeds sown too deeply in the soil or in water-logged soils face a deficiency of oxygen because the air spaces in the soil are filled with water or are too far from the surface.
$5$. Due to the lack of oxygen,aerobic respiration cannot occur,and the seed fails to produce the energy required for the emergence of the radicle and plumule,thus failing to germinate.
