Question

name the phylum of euplectella and give one reason for its placement​

Answer 1

Phylum: Porifera

Class: Hexactenellida

Scientific Name: Euplectella aspergillum

Common Name: Vensus' Flower Basket

Reason:

The Venus Flower Basket is radially symmetric and moderately sized, ranging from 7.5cm-1.3m in height. It has a unique lattice structure of fused siliceous spicules, giving it a glass-like look. A net of living tissue surrounds the siliceous spicules that is created by the amoeboid cells called archaeocytes. Within the tubular net are finger-like chambers covered in choanocytes that open into the spongocoel, allowing water to mover through the sponge. The base of Venus' Flower Basket has a tuft of elongated spicules that are used to attach to the ocean bottom. Under unfavorable conditions, reproduction is asexual. Under more favorable conditions, reproduction is likely to be sexual.
