Simple columnar epithelium - definition, structure, functions, examples

Definition of Simple columnar epithelium  The simple columnar epithelium, which is one type of epithelium, is made up of a single layer consisting of long, elongated cells. These cells are located in areas where absorption or secretion are the primary functions. The cells of the columnar epithelium can also be modified, just like cuboidal epithelium. … Read more

Hypotonic Solution - Definition, Importance, Examples

What is hypotonic solution? Definition of Hypotonic solution A hypotonic solution is one that has a lower solute concentration compared to another solution, leading to a net movement of water into the region of higher solute concentration, typically across a semipermeable membrane. What Happens to Cells when it is placed in a hypotonic Solution? When … Read more

Tonicity – Definition, Types, Examples

Tonicity Definition, Types, Examples

To function properly, cells must be kept turgid. To function properly, a well-watered plant will grow and produce fruits and flowers. A plant that is not watered for several days will wilt and eventually die. This happens because water leaves the cell and causes the cell to lose its turgidity. Based on the concentration of … Read more
