Based on the endosymbiotic theory, if a cell were to undergo endosymbiosis with a cyanobacterium, the resulting cell would be a eukaryotic cell that can make its own food. This is because cyanobacteria are photosynthetic organisms capable of producing their own food through photosynthesis. When a cyanobacterium is engulfed by a host cell, it becomes an endosymbiont and continues to carry out photosynthesis within the host cell, providing it with nutrients and energy. Over time, this symbiotic relationship eventually led to the evolution of chloroplasts in eukaryotic cells, which are believed to have originated from ancestral cyanobacteria.
Based on the endosymbiotic theory, the most likely result of the endosymbiosis of a cell with a cyanobacterium would be a eukaryotic cell that can make its own food. This is because cyanobacteria are known for their ability to perform photosynthesis, which involves converting sunlight into energy and organic compounds. This ability would provide the host cell with a source of nutrition, allowing it to generate its own food. Additionally, through the process of endosymbiosis, the cyanobacterium would become an organelle within the host cell, potentially evolving into a chloroplast, which is responsible for photosynthesis in eukaryotic cells.
