Which two structures of plants and fungi perform similar functions?

Fungi shares some function similar like plants such as interaction with other organisms, cell structure, pattern of growth and movements, and presence of root like structure.

Fungi are a multicellular organism (exception to yeast) like plants are also multicellular organism. Both share similar cell structure such as plant and fungal cell is enclosed within cell wall.

They both have nuclei which contains DNA and other cell organelles like Golgi apparatus, mitochondria and endoplasmic reticulum.

The best relationship between fungi and plant is, fungi living on plant roots and helping them to take up nutrient from the soil and receive sugar from the plants in return.

genetic variation will increase because of a new habitat and food source.

explanation:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
