  • What Are Sponges Made Out Of? From Cells to Skeleton
    Their chemical composition varies by species, consisting either of calcium carbonate (calcite) or amorphous silica (silicon dioxide) These mineralized structures are secreted by specialized cells within the mesohyl and form a supportive framework throughout the body
  • Sponge - Anatomy, Filtering, Reproduction | Britannica
    The sponges lack a well-defined organization of tissues Single layers of cells line the outer surface of the body and the internal cavities; other cells, both motile and fixed, and fibres occur in an amorphous substance (mesohyl), gelatinous in nature
