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.

Differences Between Fungi and Animals. Some fungi are single-celled organisms, such as the yeasts. All metazoans, on the other hand, have multiple cells. Even the simplest animal, the sponge, consists of many cells specialized for different tasks.All animals are motile, that is, able to move independently, at least at some stage of development.Even sessile, immobile animals such as sponges and corals have motile larvae. Fungi, on the other hand, are not able to move independently.Many types of tissue are unique to animals, such as muscles and nerves.ll animals are motile, that is, able to move independently, at least at some stage of development.
