Question

White adipose tissue contains
A. Multilocular fat cells
B. Bilocular fat cells
C. Unilocular fat cells
D. Alocular fat cells

Answer 1

Hint: The human body comprises of many different cells and tissues that function together to regulate the body. The adipose tissue is also a type of tissue located in the parietal and visceral part.

Complete Answer:
- The adipose tissue is connective tissue that is rich with lipids termed as adipocytes. It covers 20-25% of the total body weight in healthy individuals. The function of the adipose tissue is to store the energy in lipid form.
- The adipose tissue is divided into parietal or subcutaneous fat and visceral fat. The parietal fat is embedded in the connective tissue under the skin and the visceral fat is found around the internal organ like eyeballs or kidneys. It comprises extracellular matrix and cells, the main cells are termed as adipocytes, and the other cells are fibroblasts, preadipocytes, macrophages, capillary endothelial cells, and stem cells.
- Now, the adipose tissue has two types; brown fat cells and white fat cells. The white fat cells or unilocular cells or monovacuolar cells that consist of large lipid droplets that are covered by a cytoplasmic layer. Brown fat cells or pluri-vacuolar cells are polygonal and consist of considerable cytoplasm with lipid droplets scattered throughout.

Thus, the correct option is ‘C’. Unilocular fat cells.

Note: The extracellular matrix is formed by stromal cells and adipocytes. It consists of a fine network of type III collagen and its function is to hold the cells in place. The adipose tissue is composed of blood vessels and unmyelinated nerve fibers.
