These long, cylindrical unicells exhibit bilateral symmetry with blunt ends and a distinct ring-like thickening where their two halves join. When well-preserved, they offer a visually captivating sight due to the pronounced intracellular activity, particularly noticeable at the ends of the cells. In terms of reproduction, these unicells employ both asexual and sexual methods. Asexually, new cells arise from the division of the parent cell. Sexually, they engage in conjugation, a process where DNA is exchanged through nucleus fusion. This fusion results in the formation of either a hypnozygote or a zygospore. A hypnozygote remains dormant until favorable environmental conditions prompt its activation, while a zygospore acts similarly, ensuring survival through periods of adversity. These reproductive strategies contribute to the unicells’ ability to adapt and thrive in diverse ecological conditions.
