Honors Biology Final Exam 2024 with Verified Solutions What is the role of microtubules in cell division? Microtubules form the mitotic spindle, which helps separate chromosomes into daughter cells during cell division. How does the concept of endosymbiosis explain the origin of mitochondria and chloroplasts? Endosymbiosis suggests that mitochondria and chloroplasts originated from free-living prokaryotes that were engulfed by a host cell, establishing a mutualistic relationship...
