A gastrula cross section shows the early embryo folding in on itself, its outer cell layer curling inward to form the archenteron. Rows of column-shaped cells with round nuclei and speckled cytoplasm make up the ectoderm and endoderm, while short cilia fringe the outer rim. The infolding blastopore lip is easy to trace, and the inner cavity floor carries a cracked, cell-mosaic texture. Flat and disc-like, it reads well from across a room. A clear teaching piece for a biology classroom studying embryo development, or a curious specimen for a science display shelf.
