Some plants have a hard, cellulose layer protecting them. This hardened layer will prevent the detergent from breaking down the cell wall. Can you think of another way to break open the cells?   Note: The cell lysis and mashing the fruit with your hands or using a blender helps homogenize the DNA. Homogenization is the process of releasing DNA from the nuclei of the cells by breaking apart the cell walls, plasma membranes and nuclear envelope. It also helps to create a uniform mixture.

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:
