Structurally, Phragmoplasts Should Be Most Similar To

Question

Structurally, phragmoplasts should be most similar to
A) the nuclear lamina.
B) the myofilaments of muscle cells.
C) the internal support structures of microvilli.
D) the cytoskeletal elements that produce cytoplasmic streaming and amoeboid motion.
E) spindle fibers.

Accepted Answer

Phragmoplasts are structures that form during cell division in plant cells and are involved in the formation of the cell plate that separates the daughter cells. These phragmoplasts are made up of microtubules and act as scaffolds that guide the movement of vesicles containing cell wall materials to the dividing cell. Spindle fibers, also made up of microtubules, are involved in pulling the chromosomes apart during cell division and are therefore most similar to phragmoplasts in terms of their structure and function.
