Webmetaphase: [ met´ah-fāz ] the second stage of cell division (mitosis or meiosis), in which the chromosomes, each consisting of two chromatids, are arranged in the equatorial plane of the spindle prior to separation. WebAs mitosis begins, the interphase bundles of actin and the microvilli disappear, but the mitotic cells maintain a flattened shape. At metaphase the cell is still so flat that both the chromosomes and spindle apparatus are visible through the intact cell membrane. Microvilli reappear in late anaphase above the chromosomes and poles.

WebGiven that the process results in the proliferation of cells, it's important for general growth and replacement of damaged cells (e.g. the wound healing process).
