Student Project Figures Figure 5 Figure 5. Photographs of all samples at the beginning and the end of the cell aggregation process. Photographs of all sample after cell dissociation of a 4cm3 sponges pieces in 6mL of sea water in 60mm wide Petri dish. Sponge pieces were kept for 7 days either in 12:12 Light:dark cycle or in constant dark and were dissociated on day 7. (A) Photographs of cell suspension on day 7 a1-c1. Samples were treated with a 12:12 light:dark cycle for 7 days. a2-c2. Samples treated with constant dark for 7 days. (B) Photographs of cell aggregates 3.5 hours after cell dissociation on day 7. a1-c1 Samples were treated with a 12:12 light:dark cycle for 7 days. a2-c2 Samples treated with constant dark for 7 days. Photographs were taken with a Canon 70D, 18-135 mm, ƒ/9, 1/250. Figure 3 Figure 4 Figure 5 Figure 6 Figure 7
