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.
E)Microtubules of the plant cell nucleus 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 believed to play a role in the orientation and movement of cellulose-synthesizing enzymes in the cell membrane, which is essential for cell wall growth and shape. The direction of microtubules in the cytoskeleton determines the direction of cell expansion and division, which affects the final shape of the plant cell.
