Based on the descriptions given, determine what organelle you think is malfunctioning in each patient.  Name the organelle and 1-2 sentences describing why you think it’s the one described. Patient 1:  Cell division is impaired and the cell has an abnormal shape.   Patient 2:  Various chemical reactions are happening at a reduced rate and cellular export of proteins is diminished.  Patient 3:  Accumulations of old organelles and engulfed particles are making the cells crowded.   Patient 4:  Lethargy; low levels of cellular ATP.

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:
