Slide Preparation of Porifera (Sponge and Gemmules) Introduction The body wall of sponges is supported by various minute crystalline and calcareous bodies called as spicules. These are secreted by special mesenchymal cells called scleroblasts. Spicules provide taxonomic characters and are classified according to the axas and rays called as axon,…
