Answer: presence of hyphae in fungi , a long filamentous structure but plants lack hyphae.
Step-by-step explanation:
Plants and fungi are both Eukaryotic but they are different from each other.
Plants are autotrophic i.e they can produce their own food by themselves through the process of photosynthesis but fungi are heterotrophs, they cannot synthesis their food on their own.
Plants cell walls are made up of cellulose and fungi cell walls are made up of chitin.
Fungi have hyphae, a filamentous structure but plants don't have.
