One notable plant-like characteristic of certain bacteria is their ability to perform photosynthesis. Specifically, cyanobacteria, also known as blue-green algae, have the capability to convert sunlight into energy using chlorophyll, similar to plants. This process not only allows them to produce their own food but also contributes significantly to oxygen production in aquatic ecosystems.
Cyanobacteria thrive in various environments, including freshwater, marine systems, and even in symbiotic relationships with fungi and plants. Their photosynthetic activity reflects a crucial evolutionary link, illustrating how some bacteria have adapted to harness energy from sunlight in ways similar to higher plants.
