21. Cells of this zone have a stem cell function and are essential for meristem maintenance. 22. It is produced in the apical meristem and transported towards the roots in the cambium. 23. Consider a case where tolerance is achieved through activation of dormant meristems in the plants. 24. It is absorbed through the leaves and is translocated to the meristems of the plant. 25. The meristem from which the blade grows is just above the junction with the pneumatocyst. 26. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. 27. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. 28. Once AG is activated it represses expression of WUS leading to the termination of the meristem . 29. The opening of axillary buds and subsequent shoot growth is stimulated by removing the apical meristem . 30. Apical dominance occurs because the shoot apical meristem produces auxin which prevents axillary buds from growing.
