Some of the protozoans movements are described here – 1- Amoeboid movement WebGeneral features of fungi are as follows: Fungi are eukaryotic, non-vascular and non-motile organisms. The growth rate of fungi is slower than that of bacteria. Fungi grow best in an acidic environment. The Kingdom Fungi consist of both unicellular (e.g. Yeast, Molds) and multicellular (e.g. mushrooms) organisms.
