A gonimoblast is a type of cell produced by red algae upon the fertilization of a zygotic nucleus, and involved in the formation of carpospores.
The cells subsequently divide and ultimately serve as storage or generative cells.
Storage cells contain starch and are multinucleate; whereas generative cells are situated further from the auxiliary cell, are uninucleate, and form the terminal lobes in the ensuing carpospores.
[1] Gonimoblasts are connected by septal pores, usually blocked by septal plugs.
