a collagen fibers - yellow b fibroblasts - blue
c mast cells - purple d macrophages - orange
e elastic fibers - green (shade over the line)
f blood vessels and blood cells - red
g fat cells - pink
h ground substance - white
match the structure to its function

1. ____ stores energy and cushions
2. ____ production of new fibers
3. ____ consumes debris and foreign objects
4. ____ fiber that makes up tendons
5. ____ deliver oxygen to cells
6. ____ releases chemicals during an allergic reaction
7. ____ fills the spaces of the matrix (in the background)

Explanation:

1. Fat cells (adipocytes) store energy in the form of fat and provide cushioning. So the function "Stores energy and cushions" matches fat cells (G).
2. Fibroblasts are cells that produce and maintain the extracellular matrix, including fibers. So "Production of new fibers" matches fibroblasts (B).
3. Macrophages are phagocytic cells that consume debris, foreign particles, and pathogens. So "Consumes debris and foreign objects" matches macrophages (D).
4. Collagen fibers are strong and make up tendons among other connective - tissue structures. So "Fiber that makes up tendons" matches collagen fibers (A).
5. Red blood cells in blood vessels transport oxygen to cells. So "Deliver oxygen to cells" matches blood vessels and blood cells (F).
6. Mast cells release chemicals like histamine during allergic reactions. So "Releases chemicals during an allergic reaction" matches mast cells (C).
7. Ground substance fills the spaces in the extracellular matrix. So "Fills the spaces of the matrix (in the background)" matches ground substance (H).

Answer:

1. G. fat cells
2. B. fibroblasts
3. D. macrophages
4. A. collagen fibers
5. F. blood vessels and blood cells
6. C. mast cells
7. H. ground substance
