Figure 1From: Variations in morphology and PSII photosynthetic capabilities during the early development of tetraspores of Gracilaria vermiculophylla (Ohmi) Papenfuss (Gracilariales, Rhodophyta)Cruciate development of a G. vermiculophylla tetraspore. This is the main type of division (98.4% ± 0.0045), and it is characterized by the crossing of the first and second cleavage furrow. A, Freshly released tetraspores; B-H, Various developmental phases at 12 hour intervals; I-L, Various developmental phases at 24 hours intervals. Scale bar = 30 μm.Back to article page
