What is the difference between Lichen and Fungi?

Lichen:

1. Lichens are composite organisms composed of algal (phycobiont) and fungal(mycobiont) partners.

2. Here thallus organization is complex type with upper cortex, medulla, lower cortex and root-like rhizines.

3. The partners are intimate combination, showing mutualism or symbiosis.

4. Special structures like isidia, soredia, etc. are formed for vegetative reproduction.

Fungi:

1. Fungi are non-chlorophyllous thallophytes.

2. Thallus is mycelia, made up of threads-like hyphae.

3. These are heterotrophs, live either as saprophytes or as parasite.

4. No such structure is found in fungi.
