Detailed explanation-1: -When root or shoot grows in length some apical meristem leaves some meristematic cells behind at the node. Such meristems are called as intercalary meristems. They possess the same capacity as apical meristems. Therefore, both assertion and reason are correct.
Detailed explanation-2: -Apical meristems are found in root and shoot tips and are responsible for the increase in the length of the plant. Intercalary meristems are found at the bases of young leaves and internodes. They are mainly responsible for further lengthening of stems and leaves.
Detailed explanation-3: -Assertion: Apical and intercalary meristems contribute to the growth in length while the lateral meristems bring an increase in the girth of the plant. Reason: Apical and intercalary meristems always increase the height of the plants.
Detailed explanation-4: -Intercalary meristem is a type of primary meristematic tissue containing cells that can divide and promote the growth of the plant. They are located at the base of internodes. The function of the intercalary meristem is to promote the lengthening of the stem and increase the height of the plant.
Detailed explanation-5: -Apical meristem is responsible for increase in length of the plant.
