The surface zone has the ocean's least dense water and represents approximately 2% of the total volume of ocean water. The surface zone usually ranges between depths of 500 feet to 3,300 feet below ocean surface, but this can vary a great deal.
A hypha (plural hyphae, from Greek á½ÏÎ®, huphá¸, âwebâ) is a long, branching filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Yeasts are unicellular fungi that do not grow as hyphae.
1.The hyphae and the mycelium are parts of fungi anatomy. The hypha is the building block of a fungus. On the other hand, mycelium refers to the collection of hyphae in a fungusâ body. 2.Hyphae are often described as strands, threads, or filaments because of their appearance.
