QUESTION 5 Which type of epithelia would make up an organ that needed to be able to expand to many times it's normal size? Pseudostratified columnar Simple cuboidal Transitional Simple squamous QUESTION 6 You look under a microscope at 400X magnification and see an empty space lined with multiple layers of cells with flattened nuclei, and a large amount of cell free protein facing the empty space. This would be classified as: Transitional epithelium Simple squamous epithelum Non- keratinized squamous epithelium This is not epithelial tissue. Keratinized stratified squamous epithelium

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.
