They provide nutritive support to developing oocytes (young eggs) and participate in forming the vitelline envelope. Characteristics: These cells are 20–30
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) auxiliary cell
In some species, this cell is part of a specialized, branched structure called an "auxiliary cell ampulla". They provide nutritive support to developing oocytes (young
