What gives a cell its shape and is made of protein fibers?
cytoskeleton
What cell parts are made of protein fibers?
Cell parts made of protein fibers include the cytoskeleton, which consists of microfilaments, intermediate filaments, and microtubules. These protein fibers provide structural support, aid in cell shape maintenance, and facilitate cell movement. Additionally, they play crucial roles in intracellular transport and cell division.
What are spindle fibers made of?
Spindle fibers are made of microtubules, which are long, thin protein structures made of tubulin. These fibers play a vital role in the segregation of chromosomes during cell division.
Spindle fibers are made of hollow tubes of protein called what?
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.
Framework of filaments and fibers involved in cell support and movement?
The cytoskeleton is the framework of filaments and fibers within a cell that provides structure, support, and aids in cell movement. It consists of three main components: microfilaments (actin filaments), intermediate filaments, and microtubules. These components work together to maintain cell shape, facilitate cellular transport, and enable cell motility.
What is the organelle that provides the internal structure for a cell?
The organelle that provides internal structure for a cell is the cytoskeleton. It is made up of protein fibers that give the cell shape, help with cell movement, and provide a framework for organelles to be organized within the cell.
What are spindle fibers made from?
Spindle fibers are made from microtubules, which are composed of tubulin protein subunits. These microtubules play a vital role in cell division by helping to separate chromosomes during anaphase.
Spindle fibres are composed of?
Spindle fibers are composed of microtubules, which are long, filamentous structures made up of tubulin protein subunits. These fibers play a crucial role in separating chromosomes during cell division by attaching to the chromosomes and guiding their movement to opposite poles of the cell.
What is the structure for spindle fibers?
During the metaphase of cell division, the spindle fibers radiate from the centrioles at the opposite poles of the cell. When the spindle fibers start to pull the chromosomes to opposite poles, this marks the anaphase of cell division.
What are the three types of protein fibers found in connective tissue And what do they all contain?
The three types of protein fibers found in connective tissue are collagen fibers, elastic fibers, and reticular fibers. Collagen fibers provide strength and structural support, elastic fibers allow for stretch and resilience, and reticular fibers form a supportive framework. All these fibers contain proteins that contribute to the overall function and integrity of the connective tissue. Specifically, collagen is made of collagen proteins, elastin comprises elastic fibers, and reticular fibers are primarily composed of type III collagen.
The fibers in the extracellular matrix of connective tissue are made of?
protein
What are spindle fibers made of hollow tubes made of protein called?
microtubules
