Collagen

Answer 1

Promotes elasticity and cell structure as well as adhesion

Question 2

Proteoglycan

Answer 2

Promotes cell signaling and regulation, hydration and compression resistance

Question 3

Integrins

Answer 3

Holds cell in place, perform cell-cell adhesion

Question 4

Laminins

Answer 4

Anchors cells

Question 5

Microfibrils

Answer 5

Contribute to tissue elasticity and strength

Question 6

Pectins

Answer 6

Attract and hold water, used for compression resistance and adhesion

Question 7

Secondary cell wall (lignin)

Answer 7

Very stiff and strong cell wall

Question 8

Tight Junction

Answer 8

In animal cells, a watertight barrier that connects adjacent cells together very tightly.

Question 9

Desomosomes

Answer 9

In animal cells, anchor adjacent cells, provide lots of adhesion

Question 10

Gap junctions

Answer 10

Found in animal cells, gapes in the plasma membrane that allow communication

Question 11

Plasmodesmata

Answer 11

Found in plant cells, gaps in the cell wall that allow adjacent plants to communicate
