ment 1 (Chapter 1-3) i Click and drag each label to identify which phase of meiosis it describes. A haploid cell with single-stranded chromosomes results. Tetrads align at the equatorial plane. Unpaired chromosomes align on the equatorial plane. Homologous chromosomes separate and migrate to opposite poles of the cell. Chromosomes cross over to combine their genes. Sister chromatids migrate to opposite poles of the cell. Zoom W 7
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:
Drag each label to identify wish pahse of meiosis it describes
Meiosis is a type of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Somatic cells in humans are diploid, with two sets of chromosomes (one from each parent). To sustain this state, the egg and sperm that combine during fertilisation must be haploid, meaning they have a single set of chromosomes. During meiosis, each diploid cell divides twice to produce four haploid daughter cells — the gametes.
