In plant cells, which structure is responsible for the organization of spindle fibers during mitosis, given the absence of centrioles?
Show answer and explanation
Correct answer: Polar caps (MTOCs)
Higher plants are 'anastral' and lack centrioles. Instead, they use specialized regions of the cytoplasm called Microtubule Organizing Centers (MTOCs) or polar caps to assemble the mitotic spindle.
