hyphae

Description :

Fungal hyphae are the tubular structures in which fungal cytoplasm is often located. These structures grow, extending at their tips, with cytoplasm moving forwards to the growing tips. The hyphae usually have cross walls - the space between cross walls sometimes being called cells . However, the cross-walls usually have pores and cytoplasm including nuclei can pass through the pores. The two hyphae to the top are empty of cytoplasm and the cross-walls are very evident. the hypha below still has cytoplasm in it. Phase contrast.
