Which property is most consistent in all connective tissues?

• A. Presence of a large amount of extracellular matrix
• B. Lack of blood supply
• C. Ability to conduct electrical impulses
• D. High cellularity

Answer: (A)

Verified step by step guidance

1. Understand the basic characteristics of connective tissues. Connective tissues are one of the four main types of tissue in the body, and they serve to support, bind together, and protect tissues and organs.
2. Identify the key components of connective tissues. These tissues are characterized by having cells embedded in an extracellular matrix, which is composed of protein fibers and ground substance.
3. Recognize the significance of the extracellular matrix. The presence of a large amount of extracellular matrix is a defining feature of connective tissues, providing structural and biochemical support to the surrounding cells.
4. Consider the other options provided in the problem. Lack of blood supply is not consistent across all connective tissues, as some, like bone, are highly vascularized. Ability to conduct electrical impulses is a property of nervous tissue, not connective tissue. High cellularity refers to tissues with a high density of cells, which is more characteristic of epithelial tissues.
5. Conclude that the most consistent property in all connective tissues is the presence of a large amount of extracellular matrix, which distinguishes them from other tissue types.
