Where might a parasitic protozoan live Brainpop?
They live in saltwater environments. They are single-celled organisms. Which term best describes algae?
What term best describes algae?
In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in moist situations on land.
Are downy mildew and water mold protozoans?
There are three phyla of fungus-like protists. Two of these phyla consist of slime molds. Slime molds have characteristics of both protozoans and fungi and are classified by the way they reproduce. Water molds and downy mildews make up the third phylum of fungus-like protists.
What is the name of the hair like structures on some protozoans that are used for movement?
Cilia – tiny hair like structures that cover the outside of the microbe. They beat in a regular continuous pattern like flexible oars. Flagella – long thread-like structures that extend from the cell surface. The flagella move in a whip-like motion that produces waves that propel the microbe around.
How do protists eat?
Protist Nutrition Protists get food in one of three ways. They may ingest, absorb, or make their own organic molecules. Ingestive protists ingest, or engulf, bacteria and other small particles. Photosynthetic protists use light energy to make food.
Are algae protists?
Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, algae contain chlorophyll and make food by photosynthesis.
What diseases are caused by Oomycota?
The oomycetes, also known as “water molds”, are a group of several hundred organisms that include some of the most devastating plant pathogens. The diseases they cause include seedling blights, damping-off, root rots, foliar blights and downy mildews.
Does Phytophthora cause downy mildew?
Downy mildew is commonly caused by members of the oomycete genus Sclerospora, but other pathogens include species of Bremia, Peronospora, Phytophthora, Plasmopara, and Pseudoperonospora.
What is Protozoology in microbiology?
Definition. A branch of biology that studies protozoa, which are eucharyotes characterized by being single-celled, most of them motile and heterotrophic. Supplement. Protozoology is a branch of biology that deals with protozoa.
Are protists asexual?
Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as binary fission, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
