Sclerocytes are specialized cells found in certain organisms, particularly in sponges. Their primary function is to produce spicules, which are small, needle-like structures that provide support and protection to the sponge's body. These spicules can be made of various materials, including silica or calcium carbonate, depending on the species. In addition to their structural role, sclerocytes contribute to the overall architecture of the sponge, helping to maintain its shape and integrity. The presence of sclerocytes and their spicules is essential for the sponge's ability to thrive in various aquatic environments, offering both physical support and defense against predators.
