B
Microtubules.
C
Tight junctions.
D
Microfilaments.
Verified step by step guidance1
Understand the components of the cytoskeleton in eukaryotic cells: The cytoskeleton is composed of three main types of protein filaments: microfilaments, intermediate filaments, and microtubules.
Microfilaments are composed of actin and are involved in cell movement and shape changes.
Intermediate filaments provide mechanical support for the cell and help maintain its shape.
Microtubules are composed of tubulin and are involved in cell division, intracellular transport, and maintaining cell shape.
Recognize that tight junctions are not part of the cytoskeleton. They are specialized connections between adjacent cells that prevent the passage of materials between cells, thus not contributing to the structural framework of the cell.
