How are microtubules thought to affect cell shape in plants?
A)Microtubules of the plant cell cortex are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane,which,in turn,affect cell wall growth and shape.
B)Microtubules of the plant cell vacuole are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane,which,in turn,affect cell wall growth and shape.
C)Microtubules of the plant cell cortex are thought to affect the movement of lipid-synthesizing enzymes in the cell membrane,which,in turn,affect cell wall growth and shape.
D)Microtubules of the plant cell wall are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane,which,in turn,affect cell wall growth and shape.

Question

Quizplus · Accepted Answer

Microtubules of the plant cell cortex are known to guide the movement of cellulose-synthesizing enzymes to specific regions of the cell membrane, where the enzymes facilitate the deposition of cellulose microfibrils in the cell wall. This process determines the shape and rigidity of the cell wall, which in turn affects cell shape.
