( ) The preprophase band, composed of microtubules and actin filaments, marks the site of cytokinesis in plant cells. ( ) In some cell types, the site of contractile-ring formation is determined before mitosis. ( ) The early cell plate in dividing plant cells appears after phragmoplast formation. ( ) The membrane required for the newly formed cell plate in plant cells is provided by endocytosis from the equatorial plasma membrane.
