What do kingdom fungi and kingdom Plantae have different?

Very briefly, plants have cells that are interconnected with cytoplasm that flows between cells. Each cell is bounded by a cellulose wall. Each cell has a large vacuole (hole) in the cytoplasm that can occupy most of the cell space with the nucleus in the vacuole, held in place by strands of cytoplasm. Many plant cells have chloroplasts.

Fungi do not really have cells, as such. They have long tubes called hyphae which are only occasionally divided by walls. Many of these walls only partially close off the hyphae. The sections of hyphae have many nuclei rather than the one nucleus that cells have and never chloroplasts. Fungal hyphae have a cell wall made from chitin.

There are other differences as well if you want to get involved with cell biology, sexual systems, et al. Fungi are more like animals than plants in most ways.

Humans belong in the Animalia kingdom. Fungi and plants are very different from each other. Fungi are a group of unicellular or multinucleate organisms that live and grow on decomposed matter. They are also a member of the Eukaryota domain, while belong to the Fungi kingdom. Though originally they were placed in the Plantae kingdom due to its resemblance to plants, it was classified into a separate kingdom when evidence showed that it resembled the Animalia kingdom more than plants
