The kingdoms that include both unicellular and multicellular organisms are Protista and Fungi.
Protista is a diverse kingdom that includes organisms like algae, amoebas, and paramecia. Some protists, such as algae, can be multicellular, while others, like amoebas, are unicellular.
Fungi also include both unicellular and multicellular organisms. Yeasts are examples of unicellular fungi, while mushrooms and molds are examples of multicellular fungi.
These kingdoms demonstrate the diversity of life, showing that organisms can vary greatly in their complexity and structure.
