What type of structural adaptation do microvilli represent?
Understand the Problem
The question is asking about the structural adaptation that microvilli represent, specifically in the context of cellular or anatomical structures. It offers multiple-choice answers that relate to the modifications seen in epithelial tissue and plasma membranes.
Answer
Microvilli are a structural adaptation that increases the cell's surface area.
Microvilli represent a structural adaptation that increases the surface area of cells, facilitating absorption and diffusion processes.
Answer for screen readers
Microvilli represent a structural adaptation that increases the surface area of cells, facilitating absorption and diffusion processes.
More Information
Microvilli increase the cell's surface area significantly, thereby optimizing the absorption and secretion functions of the cells. This makes them particularly important in cells involved in absorption, such as those in the small intestine.
Tips
A common misunderstanding is confusing microvilli with cilia. While both are protrusions on the cell surface, cilia are usually involved in movement, while microvilli are primarily involved in absorption.
