Detailed explanation-1: -Root apical meristem and shoot apical meristem are responsible for primary growth of the plants.
Detailed explanation-2: -Primary growth results in the increase in length of the primary plant body. Primary growth occurs at the apical meristem (a meristem located at the tip of a stem). A meristem is a region of undifferentiated cells from which new cells arise through cellular division.
Detailed explanation-3: -(B) Apical meristems and intercalary meristem are primary meristems.
Detailed explanation-4: -Primary growth involves the root apical meristem, primary meristems, and primary tissues.
Detailed explanation-5: -The apical meristem is a group of cells that retain the ability to continue divisions, forming new cells continuously as the plant grows. This PRIMARY growth is responsible for growth in height.
