Final answer:
Fungi and plants are both comprised of eukaryotic cells. However, fungi have a cell wall made of chitin and are heterotrophic, lacking the ability to photosynthesize, whereas plants have cell walls of cellulose and can photosynthesize due to chloroplasts.
Step-by-step explanation:
Regarding the question, which characteristics are common to both fungi and plants: Only eukaryotic cells are common to both. Fungi and plants are fundamentally different in terms of their cellular structures and processes, but they share the characteristic of being made up of eukaryotic cells.
While plants have a cell wall made of cellulose, fungi have cell walls composed of chitin. As for the ability to photosynthesize and the presence of chloroplasts, these are unique to plants; fungi do not have the capability to photosynthesize because they lack chloroplasts. Instead of being autotrophic like plants, fungi are heterotrophic, meaning they obtain their nutrition by absorbing nutrients from their external environment.
