The microtubules area)Found in both prokaryotic and eukaryotic cellsb...
The correct answer is option 'C': microtubules are hollow, unbranched cylindrical structures found only in eukaryotic cells.
Microtubules are one of the major components of the cytoskeleton, a dynamic network of protein filaments that provides structural support and plays a crucial role in cell division, cell shape maintenance, intracellular transport, and cellular movement.
Here is a detailed explanation of why option 'C' is the correct answer:
Microtubules in Eukaryotic Cells:
- Eukaryotic cells, such as animal, plant, and fungal cells, possess a well-defined nucleus and various membrane-bound organelles. These cells have a cytoskeleton that consists of three main components: microtubules, microfilaments, and intermediate filaments.
- Microtubules are composed of tubulin protein subunits, which polymerize to form a hollow, unbranched cylindrical structure with a diameter of about 25 nanometers.
- The tubulin subunits arrange themselves in a repeating pattern, forming 13 parallel protofilaments that run along the length of the microtubule.
- The microtubules in eukaryotic cells are highly dynamic structures that can rapidly assemble and disassemble, allowing them to participate in various cellular processes.
- They serve as tracks for the movement of organelles, vesicles, and other cellular components through a process called motor protein-driven transport.
- Microtubules are also essential for cell division, as they form the mitotic spindle that segregates chromosomes during mitosis and meiosis.
- Additionally, microtubules are involved in maintaining cell shape, providing structural support, and forming specialized structures like cilia and flagella.
Microtubules in Prokaryotic Cells:
- Prokaryotic cells, such as bacteria and archaea, lack a nucleus and membrane-bound organelles. They have a simpler cytoskeleton compared to eukaryotic cells.
- Prokaryotic cells do not possess true microtubules like those found in eukaryotes.
- However, they do have a cytoskeletal protein called FtsZ, which forms a ring-like structure during cell division. FtsZ is functionally similar to tubulin but is not structurally related to microtubules.
Therefore, the correct answer is option 'C': microtubules are hollow, unbranched cylindrical structures found only in eukaryotic cells.
