Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.
Compare an epithelial cell and a root hair cell?
Epithelial cells and root hair cells serve distinct functions and have different structures. Epithelial cells form protective layers covering surfaces and organs, characterized by tightly packed cells that regulate absorption and secretion. In contrast, root hair cells are specialized for nutrient and water absorption in plants; they have elongated projections to increase surface area and enhance uptake from the soil. While epithelial cells are involved in various bodily functions, root hair cells are specifically adapted for their role in the plant's root system.
Which kind of cell is also called an epithelial cell?
Epithelial cells are a type of cell that lines the surfaces and cavities of our body, providing protection, absorption, and secretion functions. They can be found in tissues like our skin, intestines, and respiratory tract.
What is the cell extension that assists epithelial cells in absorption?
The cell extension that assists epithelial cells in absorption is called a microvillus. Microvilli are tiny, finger-like projections on the surface of epithelial cells, particularly in the intestines, that increase the surface area available for absorption. This enhancement allows for more efficient nutrient uptake from the lumen of the digestive tract. Collectively, these structures form a brush border that plays a crucial role in digestive processes.
Projections of the plasma membrane of a mucosal epithelial cell?
The plasma membrane of a mucosal epithelial cell can form microvilli, which are finger-like projections that increase the cell's surface area for absorption. It can also have tight junctions, which are responsible for creating a barrier that prevents leakage of material between cells. Additionally, the plasma membrane may contain cilia, which are hair-like structures that help with movement and sensing in certain epithelial cells.
How is a epithelial cell adapted to remove dirt from people's lungs?
A ciliated epithelial cell is adapted to remove dirt from people's lungs.
How is the epithelial cell adapted for its job?
It has small hairs called cilia which trap dust and microbes and the epithelial tissue covers the whole of the surface body.

Location of nucleus in columnar epithelial cell?
The nucleus in a columnar epithelial cell is typically located towards the base of the cell, closer to the basement membrane. This positioning allows for efficient packing of organelles in the apical region of the cell, facilitating secretion and absorption functions of the cell.
An epithelial cell can be divided into two functional regions They are the surface and the surface?
An epithelial cell can be divided into two functional regions: the apical surface, which faces the external environment or a body cavity, and the basolateral surface, which interacts with neighboring cells and the extracellular matrix. These regions are important for different functions such as absorption, secretion, and cell-cell communication.
What Cells are adapted to perform specific functions . which terms refers to this capability?
Cells that are adapted to perform specific functions are referred to as "specialized cells." These cells exhibit unique structures and characteristics that enable them to effectively carry out particular roles in an organism, such as muscle cells for contraction, nerve cells for signal transmission, and epithelial cells for protection and absorption. This capability is known as "cell specialization" or "cell differentiation."
Does the epithelial cell absorb water?
Epithelial cells primarily function to form protective barriers and facilitate absorption of nutrients rather than directly absorb water. However, in certain tissues, like the intestinal epithelium, water absorption occurs alongside the absorption of nutrients through osmosis and active transport mechanisms. Additionally, in the kidney's collecting ducts, epithelial cells regulate water reabsorption under the influence of hormones like antidiuretic hormone (ADH). Thus, while epithelial cells can be involved in water absorption, it depends on their specific location and function within the body.
What kind of cell is also called am epithelial cell?
Epithelial cells are a type of cell that form the layers of epithelial tissue, which lines surfaces and cavities throughout the body. These cells play crucial roles in protection, absorption, secretion, and sensation. Epithelial cells can be classified into different types based on their shape (squamous, cuboidal, columnar) and the number of layers (simple or stratified). They are found in various organs, including the skin, respiratory tract, and gastrointestinal system.
