Added to this they also help in determining the shape of the cell, movement of the cell, and transportation of the cytoskeleton structures play an very important role in the direction of cell division and differentiation. Many of the components also help in chromosomal movement and cytokinesis.
Cells also contain the bodyâs hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts, listed in alphabetical order: Cytoplasm. Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus. Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cellâs structural framework. The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move. It also provides a track-like system that directs the movement of organelles and other substances within cells. Endoplasmic reticulum (ER) This organelle helps process molecules created by the cell. The endoplasmic reticulum also transports these molecules to their specific destinations either inside or outside the cell. The Golgi apparatus packages molecules processed by the endoplasmic reticulum to be transported out of the cell.
