Molecules are held together by electrons shared between bonded atoms. For example, consider the formation of an H2 molecule from two separate hydrogen atoms: 2 approachinghydrogen atoms(2 H) a hydrogen molecule(H2) As the two atoms approach, each nucleus begins to attract the other atom's electrons.

Hyphae can have cross walls called septa, or lack cross walls (nonseptate; aseptate; coenocytic). The type of hyphaeâseptate or aseptateâis characteristic of specific groups of fungi. In fungi that form septate hyphae, there are perforations at the septa, called septal pores, which allow the movement of cytoplasm and organelles from one compartment to the next.
