The cell in the very center is in the phase of mitosis known as prophase. The chromosomes are coiled and are randomly arranged in the cell center. Just above the prophase cell is a cell that is just ending telophase- with daughter cells forming. Following meiosis, sperm and egg cells potentially combine during fertilization to form a fertilized egg called a zygote. When viewed under the microscope, the stages of meiosis can appear very similar to those of mitosis, so phases of meiosis will not be shown here.
Tumors Uncontrolled replication of cells leads to cell overgrowths, that is tumors .
Tumors can be classifed as benign or malignant. Benign tumors are simply excessive cell growths that will not cause any significant harm. Malignant tumors , that is cancers , are cell growths where the cells are replicating without any inhibition of cell growth, and they will cause death to the organism if allowed to continue growing. Here are the naming conventions used for the more common tumors. Sarcomas are cancers of connective tissues.
