Directions : In the following question, the Assertions (A) and Reason...
Assertion: Stratified epithelial cells have limited role in secretion.
Reason: Stratified epithelial cells provide protection to the body against mechanical and chemical stresses.
The correct option is B, which states that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
Explanation:
Stratified epithelial cells are a type of tissue that consists of multiple layers of cells. They are found in areas of the body that are subjected to mechanical and chemical stresses, such as the skin, lining of the oral cavity, esophagus, and vagina. These cells serve primarily as a protective barrier against external factors and do not have a significant role in secretion.
Role of Stratified Epithelial Cells:
1. Protection: The main function of stratified epithelial cells is to provide protection to the underlying tissues against mechanical and chemical stresses. The multiple layers of cells act as a barrier, preventing the entry of harmful substances and pathogens.
2. Mechanical Stress: Stratified epithelial cells are able to withstand mechanical stress due to their layered structure. They can stretch and contract without tearing, allowing them to adapt to movements and changes in the surrounding environment.
3. Chemical Stress: The cells also provide protection against chemical stresses, such as acids, bases, and toxins. The multiple layers of cells act as a barrier, preventing the penetration of harmful substances into the underlying tissues.
4. Absorption and Secretion: While stratified epithelial cells are not primarily involved in secretion, some regions of the body with stratified epithelial cells do have glands that secrete substances. For example, the sweat glands in the skin and the salivary glands in the oral cavity are located within regions of stratified epithelial cells. However, the stratified epithelial cells themselves do not have a secretory function.
5. Regeneration: Stratified epithelial cells have a high regenerative capacity, allowing for the repair and replacement of damaged or lost cells. This is important for maintaining the integrity of the protective barrier.
In conclusion, stratified epithelial cells primarily serve as a protective barrier against mechanical and chemical stresses. While some regions of the body with stratified epithelial cells have glands that secrete substances, the stratified epithelial cells themselves have a limited role in secretion.
Reason: Stratified epithelial cells provide protection to the body against mechanical and chemical stresses.
The correct option is B, which states that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
