Question

Does Nostoc concurrently perform photosynthesis and nitrogen fixation?


Open in App
Solution

Nostoc:

  1. Nostoc is not a bacteria, plant, or member of the animal kingdom, is a cyanobacterium instead.
  2. Nostoc is a genus of photosynthetic blue-green algae (cyanobacteria).
  3. Similar to bacteria, cyanobacteria are small, single-celled creatures without a cell nucleus.
  4. Filaments are single-celled, thread-like structures produced by Nostoc cyanobacteria.
  5. Chlorophyll, a pigment necessary for photosynthesis, is found in Nostoc.
  6. It can also play a role in the fixing of atmospheric nitrogen, making it available to plants in a form they can use. These nitrogen fixers are non-symbiotic. As a result, they carry out both concurrently.
