Final answer:
The leaf meristem is not a primary meristem.
Step-by-step explanation:
The primary meristems in plants are the protoderm, ground meristem, and procambium. These meristems give rise to the three main types of tissue in plants: the epidermis (dermal tissue), ground tissue, and vascular tissue (xylem and phloem). Each meristem is responsible for the growth and development of its respective tissue type. The leaf meristem is not a primary meristem, as leaves are not a primary tissue type.
