WebThe cells of malignant tumors arecharacterized by wide changes of parenchymal cell differentiation fromwell differentiated to completely undifferentiated. Normal cells thatare grown in culture tend to display a feature called cell density–dependent inhibition, in which they stop dividing after the cellpopulation reaches a particular density. WebMar 26, 2024 · Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.
