Diatoms locomotion type
Did you know?
WebLocomotion: All diatoms with raphe are motile. Most of the members of the order Pennales contain raphe and perform gliding movement. The gliding movement is caused by the circulation of cytoplasm within the raphe by the release of mucilage. The rate of movement varies from 02-25 µm/sec. The locomotion is affected by temperature, light etc. 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.
