Some hypersaline lakes are habitat to numerous families of halophiles. Halophiles are an interesting group of extremophiles that can survive in extremely saline environments. Some of them use sunlight to make energy, but not the same way plants do. despite the common name "prokaryote," used for both the Bacteria and the Archaea, there is evidence that suggests that the Archaea are more closely related to Eukaryotes than they are to Bacteria. An organism that can carry a parasite, and is responsible for infecting other organisms (host) with that parasite is called a _____________. The gametophyte form of the plant produces gametes, which come together and form a zygote that will develop into the sporophyte, the diploid generation of the plant. - The Great Potato Famine of the 1800s was caused by a water mold. subcellular structures are specialized to perform certain functions, which are different from the functions performed by other subcellular structures. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Their cellular machinery is adapted to high salt concentrations by having charged amino acids on their surfaces, allowing the retention of water molecules around these components. He has a master's degree in science education.

The members of the phylum Rhodophyta include mainly marine multicellular species, while freshwater or unicellular species are rare whereas Glycophytes are multicellular organisms comprising more than one cell, thus glycophytes evolved with multicellularity. Halophiles comes from the __________ words that mean "salt (halo) and loving (phile).". They believe the bacteria could survive if it encrusts itself in the salt to avoid exposure to ultraviolet light. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. What is the most convincing line of evidence for placing the Archaea in a separate domain? John Wiley & Sons Ltd, Chichester. Monera and Protista contain the two least organized organisms on earth. However, asexual reproduction is also found in lower forms. No, every single bacterium (singular) is not multicellular. While the three multicellular kingdoms are all quite distinct, they share some characteristic and not others. Why is the kingdom Protista considered to be an "artificial" grouping? The first strategy is employed by some archaea, the majority of halophilic bacteria, yeasts, algae, and fungi; the organism accumulates organic compounds in the cytoplasmosmoprotectants which are known as compatible solutes. Another example of a halophile can be found in the salty lakes of Botswana. Animal-like protists are also called __________.
