In this course students will conduct laboratory exercises to reinforce subject matter.  They will develop an understanding of the functions of the different parts of the light microscope; make drawings of typical animal and plant cells as seen under the light microscope; describe and interpret drawings and electron micrographs of the structure of membrane systems and organelles of typical animal and plant cells; make plan drawings to show the distribution of tissues within an organ, such as the dicotyledonous root; investigate the effects on plant cells on immersion into solutions of different water potentials and draw diagrams showing the different phases of mitosis and meiosis.
