Difference Between Algae And Fungi

Algae and fungi differ in their mode of nutrition. Algae are autotrophic. They have chlorophyll and perform photosynthesis. Fungi are heterotrophic, they are dependent on others for their nutrients requirement. They feed on dead and decaying organic matter.

Algae vs Fungi

Some of the algae and fungi live in a symbiotic relationship, e.g. Lichens. In lichens, the algal partner provides food to fungi and in return, fungi provide shelter to algae.

Heterotrophic mode of nutrition

They are not parasitic, have chlorophyll and make their own food by photosynthesis.

Some of the fungi are parasite

Similarities between Algae and Fungi

Following are the important similarities between algae and fungi:

  • Vascular tissues are absent in algae and fungi both.
  • Both have eukaryotic cells.
  • Asexual reproduction by fragmentation occurs in both algae and fungi.
  • Reproductive organs lack a protective covering.


Algae and fungi differ remarkably in their structure and mode of nutrition. They do coexist as lichens in a symbiotic relationship.
