17. The structural mechanism that dictates cytokinesis in a plant cell involves the alignment of Golgi-derived vesicles along the equator to build a

A. Cleavage furrow
B. Contractile ring
C. Cell plate (phragmoplast)
D. Pellicle layer

📝 Explanation

The rigid cell wall prevents pinching; instead, the phragmoplast guides Golgi vesicles to fuse at the equator, forming a new cell plate from the inside out.

📖 Additional Information
