Mitosisis divided into phases. Match the phase to its characteristic. Chromosomes begin to relax, and new nuclear membranes form Sister chromatids are pulled apart by microtubules of the spindle Condensed chromosomes line up in the center of the cell Nuclear membrane breaks down, chromosomes attach to microtubules Chromosomes begin to condense Cell physically divides (cytoplasm is divided)
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
