The cytoskeleton helps a cell with its movement, support, shape and cell division. In biology, a cytoskeleton is defined as a network of protein filaments found within a cell's cytoplasm.Know More
A cytoskeleton has three main types of filaments:
There are a number of different specialized structures within a cell called organelles. In order to do their job and move about the cytoplasm, the organelles attach themselves to the filaments of the cytoskeleton.
The cytoskeleton also helps to aid movement with the cell itself. Since the filaments that make up the cytoskeleton are continually being formed and disassembled, this causes internal forces that move the cell. One common example of cell movement is the sliding motion or crawling of white blood cells.
The cytoskeleton is also important in defining a cell's shape and giving it support. For the cells that do not have cell walls, the filaments of the cytoskeleton are what defines the shape of the cell. These same structures also give the cell support especially to the nuclear envelope. In the cell division process, the microtubules of the cytoskeleton aid in moving chromosomes to the second nucleus. In animal cells, the filaments help to constrict the center area between the two cells, which helps with the division process.Learn more about Cells
The biological process by which one cell divides into two or more cells is known as cell division. There are two types of cell division: mitosis and meiosis. Mitosis is the most common form of cell division and results in two identical daughter cells, while meiosis occurs in organisms that reproduce sexually and results in genetically different daughter cells.Full Answer >
The cytoskeleton moves organelles around in a cell, gives the cell shape, helps the cell to move and aids the cell during cell division. The cytoskeleton is made up of protein fibers.Full Answer >
Cell cycle checkpoints are times during the cell cycle in which the cell checks to see whether it is ready to proceed with mitosis or cell division. Checkpoints occur at three different times during the cell cycle: G1, G2 and M.Full Answer >
During cell division, a cell divides into two identical daughter cells. This process, called mitosis, has four stages: prophase, metaphase, anaphase and telophase.Full Answer >
