The extracellular matrix of animal cells
A) is composed of cellulose.
B) contains plasmodesmata.
C) limits the cell volume by remaining rigid.
D) helps orient cell movements during embryonic development.
E) acts as a barrier to disease-causing fungi.

Question

Quizplus · Accepted Answer

The extracellular matrix (ECM) of animal cells helps orient cell movements during embryonic development by providing cues for cellular migration and differentiation.

Answer: E
 The extracellular matrix (ECM) of animal cells can act as a barrier to disease-causing fungi by providing physical resistance and chemical defenses against invasion.

Note: 
A) is incorrect because cellulose is a component of the cell wall in plant cells, not the extracellular matrix in animal cells.
B) is incorrect because plasmodesmata are channels that connect adjacent plant cells, not components of the extracellular matrix in animal cells.
C) is incorrect because the extracellular matrix of animal cells is not rigid and can be remodeled by the cells that produce it.
