Classify each characteristic based on whether it describes actin filaments, intermediate filaments, and/or microtubules. Some characteristics may apply to more than one category. Short, cylindrical structures composed of 13 rows of tubulin Colchicine binds these fibers to block cell division Protein composition varies from cell to cell Act as tracks along which organelles can move Support the nuclear envelope The proteins of this fiber interact with myosin during muscle contraction Involved in cell division Take part in formation of cell-to-cell junctions Support the plasma membrane Primarily associated with movement Actin filaments Intermediate filaments Microtubules

Classify the following characteristics based on whether they are describing plant cell junctions, animal cell junctions, or both Plant Cells Connections are called plasmodesmata Desmosomes and hemidesmosomes connect to intermediate filaments of the cytoskeleton Membrane-lined channels through the cell walls of adjacent cells contain strands of cytoplasm Animal Cells Connections include tight junctions, adhesion junctions, and gap junctions Both Plant and Animal Cells Allow passage of small molecules Allow cell-to-cell communication
