2. Oomycetes are water molds fungus like protists that feed on decaying organic mateerial by absorbing nutrients through their cell walls which are made of cellulose. Water moulds or oomycetes are as a group of filamentous,unicellular protists physically resembling fungi INTRODUCTION :

3. The water molds resemble other fungi because they have branched filaments and form spores . However the water molds have cellulose in their cell walls while other fungi have chitin Oomycetes have a complex reproduction cycle which icludes flagella bear ing zoospores. Certain water molds are parasites of fish WATER MOLDS CHARACTERISTICS

4. Oomycota –the water molds. Oomycetes (a term used to refer to organisms in the phylum oomycota ) are a group of fungus like organisms that rely on water for completion of their life cycle hence the common name “water molds” ANOTHER NAME FOR WATER MOLDS:

5. water molds produce a asexual spores known as zoospores ,which move through surface water (such as rain or dew plants ). Because water moulds are aggressive plant pathogens they are economically and scientifically significant. some species can cause disease in various kinds of fishes as well. WATER MOLDS MOVE : Oomycetes also known as water molds are pathogenic microorganisms that resemble fungi and are responsible for a group of diseases affecting several plant species zoospores self propelled spores of oomycetes swim to their target using two flagella one opposite the other. FUNCTION OF WATER MOLDS :

6. CAUSES WATER MOLDS whilte water molds indicates that your pools isn’t properly balanced .and if that’s the case it’s time to pause swimming until it’s out of there,your pool is cleaned and your water is rebalanced. WATER MOLDS DISEASES: water molds properly called oomycetes are fungus like organisms.water molds cause diseases such as downy mildew pythium root rot and phytohthora root rot. the most common water molds in interioscapes are the root rots water molds produce a spore stage that is adapted to spread by swimming in water.

7. Many water molds live in fresh or brackish water or wet soils.most species are saprotrophic (i.e., they live on dead or decaying organic matter) although some cause diseases in certain fishes ,plant , algae,protozoan,and marine invertebrates .common genera include ACHLYA ,LEPTOLEGNIA AND SAPROLEGNIA.
