cytoskeleton
microtubules
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
Spindle fibers are made of microtubules, which are composed of the protein tubulin. These microtubules play a critical role in the segregation of chromosomes during cell division.
Microtubules are the cytoskeleton fibers that are straight hollow tubes of protein. They are made up of tubulin protein subunits and play a crucial role in various cellular processes such as cell division, intracellular transport, and cell shape maintenance.
C) Microtubules are hollow tubes of protein that maintain cell shape and facilitate the movement of cell organelles. They are part of the cytoskeleton and play a crucial role in cellular structure, transport, and division.
microtubules
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
Hollow tubes made of spherical protein subunits called tubulins are known as microtubules. These microtubules play a crucial role in cell structure, cell division, intracellular transport, and cellular movement in all eukaryotic cells. The dynamic assembly and disassembly of microtubules are tightly regulated in the cell.
Spindle fibers are made of microtubules, which are composed of the protein tubulin. These microtubules play a critical role in the segregation of chromosomes during cell division.
Microfilaments are thinner rods of protein that enable movement. Microtubules are hollow tubes that give rigidity and shape. Flagella and cilia have microtubules in their centers.
The microtubules that form centrioles and spindle fibers are made of tubulin protein subunits arranged in a tube-like structure. These hollow tubes provide structural support and play a crucial role in cell division by helping to organize and separate chromosomes.
Microtubules are the cytoskeleton fibers that are straight hollow tubes of protein. They are made up of tubulin protein subunits and play a crucial role in various cellular processes such as cell division, intracellular transport, and cell shape maintenance.
microtubules
Actin and microtubules are distinct structures within the cell. Actin is a protein that forms thin filaments, while microtubules are made of tubulin proteins and form a network of hollow tubes. Both actin and microtubules play important roles in cell structure and movement.
Microtubules are composed of tubulin protein subunits that polymerize into long, hollow tubes. They are essential for cell structure, intracellular transport, and cell division. Microtubules dynamically assemble and disassemble, allowing cells to quickly reorganize their structure as needed.
The cytoskeleton is a network of hollow tubes made of proteins called microtubules that provide support and maintain the shape of the cell. They are involved in various cellular functions such as cell division, intracellular transport, and movement.
Microtubules are not proteins themselves, but rather structures made up of protein subunits called tubulins. These tubulins assemble together to form long, hollow tubes that play a critical role in many cellular processes, including cell division and intracellular transport.
