Full Answer

The epithelium is one of the four major tissues in the body. It is made up of cells that are usually arranged in sheets or tubules that are connected to the underlying basement membrane. The epithelium serves as a covering for a number of internal and external surfaces of the body, and it can form glandular structures.

Different types of epithelia are classified according to the shape of the cells and whether or not the cells are layered. A simple epithelium may also appear as stratified and this type is classified as "pseudostratified epithelium." The cells that make up the epithelium are classified according to shape. These classifications are squamous (flat), cuboidal and columnar.

    What is the difference between a protozoa and a bacteria?

    A:

    Bacteria and protozoa are very distantly related, with bacteria classified as prokaryotes and protists as eukaryotes. This means that protozoa are more closely related to humans than either is to bacteria. The two organisms are structurally distinct. Bacterial cells lack a nucleus, and protozoa contain organelles, such as mitochondria.

    What is the difference between zooplankton and phytoplankton?

    A:

    The main difference between zooplankton and phytoplankton is that phytoplankton has the ability to manufacture its own food through photosynthesis or chemosynthesis. Zooplanktons are incapable of making their own food. Zooplanktons are animal planktons,while phytoplanktons are planktons that are capable of carrying out photosynthesis.
