Final answer:
Microtubules are the structures directly involved in the movement of organelles within a cell. Microtubules are the structures directly involved in the movement of organelles within a cell. These cellular "highways" work with motor proteins to transport organelles, and are also capable of quick disassembly and reformation.
Step-by-step explanation:
The structure directly involved in the movement of organelles within a cell is Microtubules. Microtubules are hollow structures composed of polymerized tubulin dimers, and they are responsible for several cellular processes, including the movement of organelles throughout the cytoplasm. Motor proteins carry organelles along microtubule tracks that crisscross the entire cell.
Microtubules are the structures directly involved in the movement of organelles within a cell. These cellular "highways" work with motor proteins to transport organelles, and are also capable of quick disassembly and reformation.
The structure directly involved in the movement of organelles within a cell is microtubules (d). Microtubules, along with motor proteins, function as cellular "highways" for the transport of organelles. When examining the cytoskeleton components, microfilaments and microtubules have the ability to disassemble and reform quickly (c), whereas only intermediate filaments do not play a role in intracellular movement (d). Additionally, microfilaments are responsible for the contraction of muscles (b), and tight junctions prevent the movement of chemicals between two adjacent animal cells (d). Furthermore, the cytoplasmic membrane is a structure that has the same general structure in Archaea, Bacteria, and Eukarya, indicating a common origin (b).
