Note 2: Blood was once considered a type of ct with fluid (as opposed to solid) extracellular material. The remaining 10% consists of cytoplasm, mitochondria, nucleus, and other organelles. Adipose tissue is composed of cells called adipocytes that collect and store fat in the form of triglycerides for energy metabolism. Adipose tissue arises from pluripotent mesenchymal cells (stem cells) and later originates from cells of the reticular connective tissue, which are capable of producing grape-like fatty tissue lobes also.
