______ increase the surface area of some epithelial cells.

  1. a. Microfilaments
  2. b. Microvilli
  3. c. Gap junctions.
  4. d. Adhering junctions

Summary Introduction

Introduction: The body tissues contain a group of specialized cells that can organize as organs. The epithelial tissue is a type of tissue that is made up of epithelial cells, and there is a sheet-like cell layer having no extracellular matrix between them. They help to cover the surface of the body and line its internal cavities and tubes. The epithelial cells can be classified into three types based upon their cell shape—cuboidal, squamous, and columnar epithelia. The major functions of the epithelial cells are secretion, absorption, protection, and sensing.

Explanation

Reason for correct answer:

The columnar and cuboidal epithelia perform secretion, absorption, and movement of materials. These epithelia consist of cells that contain microvilli. Microvillus is a hair-like structure that is projected out from the cell surfaces. They help to increase the surface area of some epithelial cells. For example, the microvilli increase the surface area of simple columnar epithelium for accessing the area for the absorption of nutrients.

Option b. is given as “microvilli”.

Microvillus is a hair-like structure that is projected out from the cell surfaces. They help to increase the surface area of some epithelial cells.

Hence, the correct answer is option b.

Reason for incorrect answer:

Option a. is given as “microfilaments”.

The thin filaments that are present in the cytoskeleton of the eukaryotic cells are called as microfilaments. They will not increase the surface area of the epithelial cells...
