Loose connective tissue specializing in fat storage is known as?

Loose connective tissue that specializes in fat storage is known as adipose tissue. This type of tissue plays a crucial role in the body by storing energy in the form of fat, providing insulation to help regulate body temperature, and offering cushioning to protect organs. Adipocytes, or fat cells, are the main cellular component of adipose tissue, allowing it to effectively perform these functions.

In contrast, the other options refer to different types of connective tissue. Cartilage is a more rigid and flexible tissue that provides structure and support to various body parts, but it does not serve the same function in fat storage. Connective tissue is a broad category that encompasses various types of tissues, including adipose, but does not refer specifically to fat storage. Dense connective tissue is characterized by its tightly packed fibers, which provide strength and support, rather than the loose nature and fat-storage capability of adipose tissue. Thus, the choice identifying adipose tissue is explicitly correct for this question.
