Biology of the Red Algae
The morphological manifestation of this nutrient- driven interaction between
gametophyte and carposporophyte generations is the structure known as the
cystocarp. The term "cystocarp" was first proposed by Kiitzing (1843, p. 100) as a

A Text-Book of Botany: Morphological and Physiological
The spores arise in the centre of this pericarp as outgrowths of the central cell,
the cells of the trichophore not participating in their formation. The trichophore is
pressed aside by the cystocarp (B, b, tg), and hence at a later period the
trichogyne ...

Major Ion Toxicity in Membrane Concentrate
Algae branch tips in the control treatment produced an average of 1 1.2
cystocarps/branch tip and showed no signs of degeneration. Mean cystocarp
production met the limit of 10 cystocarps/branch tip specified by the protocol (
USEPA 1994a).

This placental cell, gonimoblast filaments, with carposporangia and the
surrounding sheath or pericarp is called 'cystocarp', (Carposporophyte) (Fig. 6.5).
It is a partly haploid and a partly diploid structure. Cystocarp : The cystocarps are

The result of the fertilization of the carpogonium is the development of a
fructification known as a cystocarp (or sporocarp), and the different groups of the
Rhodophyceae are characterized by the method of formation of this fructification.

All of these can cause a failure of female plants to produce cystocarps, but toxic
