    Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury to them. All cells grow and die at different rates. The cell cycle can be divided into three periods: interphase‚ the mitotic phase‚ and cytokinesis. During interphase‚ the cell grows‚ accumulating nutrients needed for mitosis‚ preparing it for cell division and duplicating its DNA. During the mitotic phase‚ the cell splits itself into two distinct daughter

    the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain

    Animal cells do not have a cell wall. Instead of a cell wall‚ the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Animal tissues therefore require either external or internal support from some kind of skeleton.  Frameworks of rigid cellulose fibrils thicken and strengthen the cell walls of higher plants.  Plasmodesmata that connect the protoplasts of higher plant cells do not have a counterpart in the animal cell model.  During telophase
