Gonimoblast

Liagora magniinvolucra Fig. 9. shows an early stage in gonimoblast development showing the already extensive development of the involucre

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.^[2]
