Golgi vesicles containing non-cellulose cell wall materials like glycoproteins, pectin, hemicellulose, mucilages and other polysaccharide secretory products and components are released from the Golgi cisternae, which invade the equatorial region of the spindle and aggregate to form the cell plate. Phragmoplast helps in formation and growth of the cell plate, which is required for proper targeting of Golgi-derived vesicles to the cell plate. So the answer is
Cellulose is not found within the golgi vesicles.

Discuss the function of kinetochores in mitosis. Specifically:a) How microtubules attach sister chromatids to the spindle- discuss the “trial and error” process and how tension ensures correct attachment.b) If the “+” end of microtubules is embedded in the kinetochore, how is depolymerization and microtubule shortening possible in anaphase?
