Which statement accurately describes a feature of Kingdom Fungi?

Fungi are characterized by their cell walls, which are primarily composed of chitin. This distinguishes them from plants, which have cell walls made of cellulose. The presence of chitin is a key feature that contributes to the structural integrity of fungal cells and plays an essential role in their biology and ecology. Fungi can exist in both unicellular forms, such as yeasts, and multicellular forms, such as molds and mushrooms, but the defining characteristic remains their chitin-rich cell walls.

The other statements do not accurately describe features of Kingdom Fungi. For instance, fungi do not have the ability to photosynthesize, as they lack chlorophyll and do not perform photosynthesis like plants. Their structure is based on cellular organization rather than true tissues as found in animals and plants, and they can be either unicellular or multicellular, rather than being exclusively unicellular.
