Final answer:
Adipose tissue and loose irregular connective tissue can be classified as 'connective tissue proper', which includes a variety of cell types and protein fibers. Bone and blood are not considered connective tissue proper; bone is supportive tissue, and blood is fluid tissue.
Step-by-step explanation:
The term 'connective tissue proper' refers to a classification within connective tissue that includes various cell types and protein fibers suspended in a viscous ground substance. Connective tissue proper can be further divided into 'loose connective tissue' and 'dense connective tissue'.
Of the options given:
- Bone is a form of supportive tissue, not connective tissue proper.
- Blood is considered a fluid tissue, so it also does not fall under connective tissue proper.
- Adipose tissue is a type of loose connective tissue proper and is known for its role in storing energy and insulating the body.
- Loose irregular connective tissue is also a type of connective tissue proper, which supports organs and other structures within the body.
Therefore, both adipose tissue and loose irregular connective tissue can be classified as connective tissue proper.
