Ch. 22-2 In animals, meiosis of germ cells produces gametes. Some plant cells also undergo meiosis, but the resulting cells are not gametes. Explain what the products of plant meiosis are, what they develop into, and how plants produce gametes.

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:
