Grout haze should be removed as soon as possible after grouting the tiles. If removed in a timely manner then a simple cheese cloth or paper towel can be used to remove the grout haze. When the grout haze is allowed to sit and dry on the tiles for a longer period of time then it can be more difficult to remove.
Protista Kingdom of Eukaryotes. The kingdom Protista contains the single-celled eukaryotes in contrast to the bacteria which are examples of the prokaryotic cell type. Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues. They could be viewed as those eukaryotes that cannot be classified as one of the other cell types. They include the one-celled animal-like protozoa, one-celled algae, slime molds and water molds.
A cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism. Case in point: You. Biologists do not know of any single organism on Earth that is composed of both eukaryotic and prokaryotic cells. However, many different types of prokaryotic cells, usually bacteria, can live inside larger eukaryotic organisms. Creepy, but true.
