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.
In some species, this cell is part of a specialized, branched structure called an "auxiliary cell ampulla". auxiliary cell
It is a specialized cell on the female gametophyte that receives the diploid nucleus produced after fertilization. It is a specialized cell on the female
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) In Marine Invertebrates (e
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 is critical in the post-fertilization development of many red algae.
