Nostoc cell differs from that of E. coli in the following features :

Nostoc cell differs from that of E. coli in the following features : Correct Answer All of the above

Explanation:

Nostoc differs from the E. coli in the following ways:

  1. Nostoc is a cyanobacterium (also referred to as blue-green algae) that have photosynthetic pigment chlorophyll-a similar to green plants. The E.coli does not have any photosynthetic pigments.
  2. Due to the presence of photosynthetic pigments, the nostoc can prepare food by themselves i.e. they show autotrophic nutrition. The E. coli is a heterotroph i.e. it depends on other organisms for its food requirement.
  3. Nostoc has specialised cells called the heterocysts, which can fix the atmospheric nitrogen. The E. coli does not have any heterocysts present.

Thus, the correct option will be ''all of these''
