Some red algae are procarpic (the auxiliary cell is close to the carpogonium) while others are non-procarpic (the auxiliary cell is located far from the carpogonium, requiring long connecting filaments). 2. In Marine Invertebrates (e.g., Oysters/Bivalves)
The fertilized egg (carpogonium) produces a connecting filament that fuses with the auxiliary cell, transferring the diploid nucleus. The auxiliary cell then initiates the growth of the carposporophyte, a structure that produces spores. auxiliary cell
It is a specialized cell on the female gametophyte that receives the diploid nucleus produced after fertilization. Some red algae are procarpic (the auxiliary cell
They provide nutritive support to developing oocytes (young eggs) and participate in forming the vitelline envelope. Characteristics: These cells are 20–30 The auxiliary cell then initiates the growth of
Based on the research, "auxiliary cell" refers to a specialized, supportive cell type, primarily discussed in and marine invertebrate embryology (e.g., in some bivalves). 1. In Red Algae (Rhodophyta)
The auxiliary cell is critical in the post-fertilization development of many red algae.
