Final answer:
The cells within adipose tissue that store lipids are known as adipocytes, which include white and brown adipocytes serving functions related to energy storage, insulation, and protection.
Step-by-step explanation:
Cells within the adipose tissue that store lipids are called adipocytes. Adipose tissue is a specialized form of areolar tissue rich in stored fat, and it plays a crucial role in energy metabolism, insulation, and protection of body organs. There are primarily two types of adipocytes, namely white and brown adipocytes. White adipocytes store lipids as a single large drop and brown adipocytes store lipids as many small droplets. Brown adipocytes are also known for their high metabolic activity in contrast to the less active white adipocytes.
