Fungi cell walls contain chitin b. Fungi are closer to animals than plants c. The dominant form of the zygomycota fungal group is made up of dikaryotic cells d. Fungi can live on and in humans e. Some fungi are saprophytic and absorb nutrients from dead plant material they digest 5. Which of the following statements is true ? a. tropical habitats b.
