phototropic bacteria
Noun 1. Photosynthetic bacteria: A group of bacteria, including green and purple bacteria, that obtain energy for growth from sunlight through a process called photosynthesis. Unlike plants, their carbon source is derived from carbon dioxide or organic carbon compounds.
The term is used in scientific contexts, particularly in microbiology, ecology, and environmental science, to describe a specific physiological group of prokaryotic organisms. * Phototropic bacteria are often found in aquatic environments like stagnant ponds and sulfur springs. * The study of phototropic bacteria helps scientists understand early forms of photosynthesis on Earth.
- In Research: The term specifies a metabolic type. For example: "The sediment sample was analyzed for the presence of anoxygenic ."
- Ecological Role: These bacteria are primary producers in certain ecosystems, converting light energy into chemical energy.
- Phototroph (n): An organism that uses light as its primary energy source. are a type of phototroph.
- Photosynthetic bacteria (n): A broader synonym that includes cyanobacteria in addition to green and purple bacteria.
- Anoxygenic photosynthesis (n): The type of photosynthesis performed by most , which does not produce oxygen.
- Photosynthetic bacteria (in a broad sense)
- Phototrophic bacteria
- Green and purple bacteria
The term "phototropic" in this compound specifically refers to trophism (nutrition/energy source), not tropism (growth movement toward light). These bacteria are "phototrophic." While "phototropic" is the traditional form used in this compound name, in modern precise terminology, "phototrophic bacteria" is often used to avoid confusion with plant phototropism.
- green and purple bacteria; energy for growth is derived from sunlight; carbon is derived from carbon dioxide or organic carbon
