Question

White and brown adipose tissue

Answer 1

Answer:

In contrast to white adipocytes, which contain a single lipid droplet, brown adipocytes contain numerous smaller droplets and a much higher number of (iron-containing) mitochondria, which gives the tissue its color. Brown fat also contains more capillaries than white fat.

White and Brown Adipose Tissue:

The cells of adipose tissue are characterized by droplets of fats in the cytoplasm of connective tissue cells. There are two kinds of fatty tissues. In the white adipose tissue, there is a single large fat droplet in the cells surrounded by a small amount of the cytoplasm. The brown adipose tissue-cell on the other hand has many small droplets of fat, suspended in a considerably larger amount of cytoplasm. Whereas brown fat cells contain many mitochondria, the white fat cells have comparatively few. The colour in the brown fat is due to a high concentration of iron-containing cytochrome pigments.

Brown fat is particularly found in new-born babies and hibernating mammals. It accounts for 5-6 percent of the body weight of the new-born rabbit and also of man. Brown fat has a larger capacity for generating heat. It is because of brown fat that new-born mammals generally do not shiver inspite of lower temperature outside. Brown fat cannot be a substitute of food. Adipose tissue may be examined from the fat bodies of frog or from the skin of rabbit.
