Plants must absorb certain essential mineral elements for their normal growth and development. If an essential element is missing, it will show specific deficie
Where viable seeds can constantly respire, absorbing O2 from the air while releasing CO2, CO2 dissolves in water to form H2CO3, which is unstable and dissociate
