Introduction
Anatomy
Water Mold is one of the many organisms that is often mistaken for something else. For many years, scientists were even confused about its classification. It resembles fungi in many ways, but upon closer inspection has its own characteristics. The group tself is made of filamentous, unicellular protists. It is composed of either a mycelia or a tube-like vegetative body. The mold can preform many of its function through the rhizoids, which act like roots, absorbing nutrients. These hairlike structures prodrude from the sporangia, a small multicellular structure produced by the Water Mold.[1]
When inspecting the difference among Water Mold and fungi one of the things you will find is the cellulose contianed in the molds walls. This cellulose provides energy and nutriton to the mold, whereas the fungis walls contain chitin. Another important difference is the nuclei of these organisms. During the vegetative state, the Water Mold has a diploid nuclei, oppossed to the fungi's haploid one. There are many types of Water Mold, and the different species have different ways of producing. The ones that produce sexually have specialized regions that produce specific male or female parts.
Reproduction
Water Mold is unique in the sense that it can reproduce both sexually and asexually. This process can be as simple as a divisoin of a sporangium into individual motile, flagellated spores, or as intricate as a sexual process.[2] The word "Oomycota" actually means "egg fungi", and refers to the large round oogonia containing the female gaments. This special part is what enables some Water Mold to reproduce sexually. Water Mold is oogamous, meaning it produces large non-motile gametes called eggs, and small gametes called sperm.[3] Since the two major types of Water Mold species are Chytrid and Oomycete, there are also different ways in which they reproduce.
The Chytrids rerpoduction can be a very simple division, or the more comlicated processes of actaul reproduction. The Oomycetes have distinct parts that are male and female. These parts aid in the process of reproduction. In addition to this process, they are also able to reprode asexually.[4]
Ecology
The two major species types of water Mold have different environments that they are accustomed to. The Chytrids live mostly in salt and freshwater. They may also live in moist soil. The Oomycetes prefer a more aquatic environment. Others may live in water in certain stages of the life cycle. In genearal, Water MOld thrives on decaying plant and animal material, or parasitic foods, such asd fungi, plants, and algae. By eating these foods, the organism gets the metabolic enery needed to function properly.[5] In addition to the conditions already listed, Water Mold is highly productive in condition of high humidity and running surface water. It is in places like this, that the organisms has the best opportunity to carry on growth and a healthy life cycle.
