No, cheek cells do not have intercellular spaces.
Cheek Cell Arrangement
The question of whether cheek cells have intercellular spaces can be addressed by examining their structure and function. Cheek cells are a type of epithelial cell, specifically squamous epithelial cells, which form a protective lining. They are characterized by a flat, scale-like shape that allows them to form a tightly packed layer.
What are Intercellular Spaces?
Intercellular spaces are the gaps or spaces between cells. In many tissues, these spaces are necessary to allow for the passage of fluids, nutrients, and waste products. However, certain cell types, like squamous epithelial cells, require a very compact arrangement for their function.
The Compact Structure of Cheek Cells
- Flat and Compact Arrangement: Cheek cells form a flat, compact arrangement which is a characteristic of squamous epithelial tissue.
- No Intercellular Spaces: The cells are closely packed together, leaving virtually no intercellular spaces between them. This feature provides a continuous barrier.
- Protective Barrier: This tight arrangement helps to create a barrier that protects the underlying tissues from physical damage, as well as harmful substances and pathogens.
Practical Insight:
- Function: The main role of cheek cells is protection.
- Contrast with other tissues: Unlike other tissues where intercellular spaces are prevalent, cheek cells have a dense structure without gaps.
- Microscopy: When observing cheek cells under a microscope, the absence of visible intercellular spaces is apparent.
Conclusion
Cheek cells, specifically squamous epithelial cells, are designed to form a dense, protective layer with no intercellular spaces present. The reference explicitly states this fact, confirming the absence of spaces between these cells.
