Remarkably, it's a single cell that can grow to a length of six to twelve inches. What if we could really think of higher plants, like tomato, as one cell instead of multitudes? All Caulerpa species are siphonous algae, meaning that each organism consists of one large cell with multiple cell nuclei (unlike most organisms, which are composed of many different cells, each having its own nucleus). Phytochemistry 72:2024–2030. Fischel JL(1), Lemee R, Formento P, Caldani C, Moll JL, Pesando D, Meinesz A, Grelier P, Pietra P, Guerriero A, et al. Here, we present a de novo assembled, intracellular transcriptomic atlas for the giant coenocyte Caulerpa taxifolia. This species resembles another Hawaiian Caulerpa species, C. sertularioides. Yet Caulerpa is a plant, too, and independently evolved a land plant-like body plan, but without multicellularity and as a single cell. In fact, higher plant cells are connected to each other by means of channels called plasmodesmata, and it has been argued that multicellular land plants exhibit properties similar to single-celled organisms like Caulerpa.
