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.
The Structure of Prokaryote and Eukaryote Cells During the 1950s, scientists developed the concept that all organisms may be classified as prokaryotes or eukaryotes. The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus. Prokaryotic cells lack internal cellular bodies (organelles), while eukaryotic cells possess them. Examples of prokaryotes are bacteria and archaea.
