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.

â¢Mycology = Study of Fungiâ¢All Fungi are chemoheterotrophs âRequire organic compounds for energy and carbonâCan be aerobic (filamentous, bread mold) or facultative anaerobes (yeast) â¢Most of the 100,000 or more fungal species are decomposers of dead plant material.easts â¢Nonfilamentous unicellular fungi that are spherical or ovalâ¢Some divide by fission that can either be even or uneven cell division (budding)â¢ Candida albicans âsometimes produces buds that fail to detach into daughter cells and are called pseudohyphae. âThese can resemble hyphae and penetrate deeper tissue.
