The major route for endocytosis in most cells, and the best-understood, is that mediated by the molecule clathrin. This large protein assists in the formation of a coated pit on the inner surface of the plasma membrane of the cell.This pit then buds into the cell to form a coated vesicle in the cytoplasm of the cell.he major route for endocytosis in most cells, and the best-understood, is that mediated by the molecule clathrin.

Sponges are extremely primitive invertebrate life so are classed under the Kingdom Animalia, they do not photosynthesise so are not plants. They are also very different to fungi and have an entirely different composition and life cycle. A sponge if passed through a sieve gradually reforms its original shape.ponges are extremely primitive invertebrate life so are classed under the Kingdom Animalia, they do not photosynthesise so are not plants.

However, it is often unclear whether such fungi,lacking typical morphological adaptations, are terres-trial or truly aquatic. For example, species of Asper-gillus and Penicillium are among the most commonfungal isolates from terrestrial, freshwater, and marineenvironments, even from deep-sea sediments.naddition to lichens, zoosporic fungi and fungal-likeorganisms are found in supralittoral soils (Sparrow1968 and references therein, Ali & Abdel-Raheem2003). âAero-aquaticâ fungi form another group ofmitosporic fungi adapted to frequent drying and wet-ting cycles (Webster & Descals 1981).
